Defense is rather meaningless though, at least in those quantities. With the way it functions, it's really only worth it as a stat when going all out as each successive defense point matters more than the last, and in a game where you can infinitely heal with no negatives or much timeloss it's pretty moot relative to extra damage which would save you more time in the long run.
Also not sure what you're comparing it to but the dragontooth club and cutlass both have an inherent 50 crit power that has nothing to do with their innate enchant, so the damage on crit would be considerably lower (due to the stacking nature of the innate crit power)
And I do get what you mean about allowing players to find their own best, I will say a lot of stuff said does come down to simple matters of rhetoric though, disallowing yourself from offhandedly saying something is better, worse, etc. than another option simply because you want another to have the least impacted experience is rather pointless when it doesn't fundamentally stop them from pursuing anything themselves.
For Defense, it depends on how you look at it. The main benefits are time and money, of course. The timeloss of switching to an item, consuming it, and switching back to whatever you were doing. Which in single player isn't *so* bad but in Multiplayer is quite bad, and even in single player it's time wasted, and time is the most valuable thing there is imho. That time gained in not having to deal with it is indeed scaling in benefits, the more defense you have the more proportionally one more point will do for you, which is why I tend to indeed double down on it (again I'm planning on normally running with two crabshell rings, dragonscale boots, *and* the dwarf sword). But there is the actual raw money saved in consumable healing items, which if you're buying salads is easily measured and quite linear - for every 5 points of defense, that's 1 less salad after 10 attacks received, meaning for every 5 points of defense it's 22G saved per enemy attack on you. Given that when I'm ignoring enemies it's not uncommon for me to take 30, 40, or even 50 attacks throughout the day, that's like an extra diamond per day, or the equivalent of 5 diamond crystalariums for free just by tossing on a crabshell ring. Eventually when you're omegawealthy, sure, it doesn't even move the needle. But for early farmers that's a substantial benefit unlikely to be matched through the marginal time savings associated with switching to the other weapon.
Speaking of - the reason I'm comparing the Dwarf Sword with +75 Crit Power Inherent to the Dragontooth Cutlass / Club with +4 Speed Inherent is that the Speed is undoubtedly better on the latter ones. Especially if you're going desperado, and already doing 600+ damage on a crit, more crit damage (x11 instead of x8) will just be increased overkill damage on the vast majority of enemies, and that'll be increasingly true for every non-crit hit you get before the crit occurs. There are exceptions, quite notably the dangerous purple slime and royal serpent, but the royal serpent you're not one shotting anyway and for the dangerous purple slime it doesn't significantly change your average hits to kill. Meanwhile the +4 speed on the cutlass moves the time to attack from .4 seconds to .24 seconds, meaning you get 3 attacks off faster than you would otherwise get 2. It's a more than 50% increase in damage output over time, and a more than 33% reduction in average time to kill, across all targets, including those mentioned above. Though the club gets Less benefits than the Cutlass from speed, it's still the superior option there.
So given that assumption, that you're going speed on them, the Dwarf Sword is in a different spot. It has lower damage and needs the help on damage more, doesn't already have inherent crit power, and most importantly already has +2 speed. Which since the speed inherent is capped at +4 between the weapon speed and the inherent combined, means it's a choice between +2 speed and +75 crit power, which is a much more competitive choice. Thus at this time my assumption for the optimal choices for each is the + Crit Power Dwarf Sword (+75 Crit Power, +2 Speed, +4 Defense) vs the + Speed Dragontooth Cutlass (+4 Speed, +50 Crit Power, higher base damage). Given that, the Dwarf Sword is around 630 average damage on a crit (before things like Iridium Bands) while the Cutlass is 720. Higher, but in truth there's not a single enemy killed by 720 damage which is not also killed by 630, thus similar damage.
If you stack crit power then sure, substantial difference - 900 average damage on a crit from the cutlass at that point instead of 630 for the dwarf sword. But that kills the dangerous purple slime in 1 crit instead of 2, and is otherwise functionally identical damage still. Attacking more than 33% faster will do far more for your kill time for that particular enemy, and infinitely more for your kill time (something is infinitely better than nothing after all) in all other cases.
And I agree in general about not limiting your ability to communicate effectively by artificially limiting the language used. Note I don't think it's a problem at all to say that something is better or worse than other options, much like I'm calling out speed as the far better inherent for the dragontooth weapons here, pretty much universally. I just don't think "best" is justified in this particular case, as I'm not convinced it applies. For example, in my cropless farmer's run, right now she's using a dwarf sword with 3 aquamarines, a +75 crit power inherent, and fighter / brute. I ran the calcs and based on the low base damage of the dwarf sword, the targets I care most about (really just tiger slimes, purple slimes, magma sprites and sparkers, and serpents) it was the better option; I either OHKO with a crit or kill with a Crit + Hit for all those targets with this setup and I guarantee a 2 hit kill on serpents or a 3 hit kill on sprites instead of it being a potential 3 or 4 hit kill respectively if I don't crit. Now once I enable dangerous versions of the mines / skull cavern, that'll change, but for now this is actually the superior setup.
So for most things in general but *especially* combat context is everything.
