Tales of Vesperia is an action RPG, and veeery clunky at this point. It gets better later on, but the movement in combat is extremely stiff, and recovery times are out of this world. Sure, you can animation cancel to combo a bit faster, but that won't fix shoddy hitboxes and the AI freaking out to track targets.
FFX has a rock solid turn based system, probably the best of all the FF. Much better than the ATB of old, frankly. And the... "thing" that they have in FFXIII and FFXV.
However as games... Tales of Vesperia is just more endearing. Better locales and an actual overworld instead of corridors, nice dungeons, nice progression and exploration, FFX is definitely pretty weak and linear in that department and its puzzles are plain slow and annoying.
Same for story and characters, it's pretty slow, but ToV has a lot of funny moments and great interactions between your team members, FFX is pretty by the book and gets stupid at times, although it's not bad by any means. Not quite as good as some other FF, but decent enough.
FFX-2 is a weird ass follow up, and if gameplay wise it's pretty interesting with all the different jobs, it's kind of mess. Why they took the serious and very religious FFX to turn in into a pop star walk tour? No idea.
It's... a game... that can be played.
But still... weird.
No idea how the FF ports will fare on Switch though.
ToV does not have very good performance outside of combat (especially in the overworld), and it shares its biggest issue on all paltforms, an abuse of filters making it blurry, fuzzy, bloomy and just painful for the eyes. Image quality is really poor, and only the PC version can be modified to fix that honestly (it runs on a toaster too).
If you want an RPG on Swich, you may consider the old FFs too.
They're still pretty good, if you haven'(t played them. Slow as hell though, is there fast forward in the upcoming ports? Can't imagine playing FFIX without it now.
