Each Farm map has big advantages depending on what you want to do with it.
The Forest Farm is my general favorite as you can choose the Bat Cave and not miss out on Mushrooms as they spawn on your farm along with the other Forageable items. Like Hardwood! Spawning on your Forest Farm,
every day. Honestly if you are a little frustrated or impatient about getting some of the things done for the Community Center (which totally never happens, right? nah didn't think so), the Forest Farm really eases some of that mild annoyance. It comes with significantly less freedom than more open Farms so if you're a megaFarmer then stick to Standard or Four Corners.
Standard is simply the best blank canvas. I suck at blank canvasses as that means blank brain and I need a bit of restriction for some meager creativity to happen so I don't do Standard Farm any more.
Four Corners is great for theming or touring. In late game I pretty much always come up with a walking or riding tour of themed farm areas and 4 Croners is pretty great for that. Don't forget the "hidden" shortcut between the bottom 2 areas! I didn't know about that for
ages until someone posted it here.
Beach is so big that it's great for theming and touring but you have to be happy with minimal sprinkled Farming in early to mid game before getting Deluxe Retaining Soil. There's ~200 Sprinkled tiles to Farm which is more than enough for me so I like Beach a lot.
Haven't done a Meadowlands playthrough yet, no opinion.
Haven't done a Riverlands playthrough yet because I'm not a masochist.
Haven't done a Wilderness playthrough yet because SDV is a
chill game.
……
Hilltop.
NO.
I did Hilltop, it was OK for a while. And then it was very much not OK but Abby was there. Once she said the rocks tasted funny, that was all I needed to attempt a magical geological transformation the likes of which would send that charlatan Wizard cowering in fear. It did NOT go well the first time as my save ended up an utter mess and Hilltop thought it could get the best of me.
But I
persevered.
Which means I did nothing for over a year while I stewed. Look, it's all in the planning and stuff. I needed to calm down for like 16 months or so.
But then I did my homework and tried again and it worked! Flattened those awful hills, released the horrible trapped corners, rerouted the restrictive riverbed and ended up with a nice, mostly Standard farm with a few extra bushes here 'n there for flavor.
Afterwards Abby wondered what to do with all the open space and absently Farmer Bobbi responded, "Whatever's the opposite of that horrible, hard, restrictive terrain."
"Well, we could keep the echoes of the hill tops as a reminder of the Farm I originally trolled for frogs and Amethysts before this cute Farmer arrived. And then asked me to stay there with her. But then add something soft and fun and silly as a sign of a different— a
better future." As usual Bobbi's brain was not following anything containing euphemism so she just stood there with a blank look. Some Farmers need to be clubbed over the head with ideas before they recognize them.
"A Slime Farm you thicky-thick! Brick-shaped Hutches like the old mesas with lotsa pet Slimes inside in various shades of purple. I'll even let you pet the lavender ones!"
No Hilltop,
anything but Hilltop.
