As always, the answer is: It Depends.
Specifically, it depends on what lengths you are willing to go to, and what you are willing to invest.
Without using any fertilizer or shenanigans, Ancient Fruit wins out, plus is an easy one-day workweek. This is what most people go by because it is simple, and it just works.
However, it is theoretically possible to push starfruit to a technically more profitable position than ancient fruit but the costs are excessive and honestly probably not worth the investment. First off, it requires Hyper Speed-Gro, which itself requires a Solar Essence, three Bone Fragments, and a Radioactive Ore to craft. Now, Radioactive Ore can *ONLY* be obtained manually during Qi Challenges, which means you're going to be spending most of your time farming for the radioactive ore to make enough HSG to be capable of actualizing the theoretical yields.
The other problem with the proposed 'Starfruit can get better' is 'use agriculturalist instead of artisan'. Which is fine... until you realize that means losing that 40% flat bonus on your profit margin because you're NOT using Artisan. And if you want to use the statue in the sewer to hot-swap them out, that's an extra 20k a *week* you'll be spending micro-managing your perks, and any timing screw ups means it is all for naught anyway.
So, technically? Yes, Starfruit can *technically* get more profitable than ancient fruit. Not more profitable than Hops or fruit trees in a greenhouse can, but more profitable than ancient fruit, at least in a greenhouse or during the one month that they grow outside. If you're willing to be constantly grinding Qi Quests to keep yourself in the fertilizer needed, which also means you can't use the water retaining soil and thus actually need sprinklers by the way, and willing to settle for no Artisan bonus or a hell of a lot of micromanaging and spending of money on the perk reset statue every week.
But honestly? Just stick with Ancient Fruit. And if you're talking about not in a greenhouse, then Ancient Fruit wins anyway simply because it grows three out of the four seasons. You can have fields of hundreds of Ancient Fruit growing outside from Spring to Fall.
You can get Ancient Fruit up and running before the end of the first year, and even before you complete the entire Community Center. You need to complete a lot more content for the stuff needed to make Starfruit theoretically more profitable. You need to complete the post-CC questline, build Willy's boat, complete all of the Ginger Island content, then start doing Qi Quests to unlock the recipe and to obtain the ingredients needed.
So it depends on how much trouble you want to go through in order to start getting return on your investment. For myself, I don't consider the marginal profit increase worth the investment, but YMMV.
