For this I would advise looking at a comparison video.
On PS4 and PSVita they looked very good port, on Switch I have no idea.
I'll have to look into the PS4 version as I don't have a Vita. I'm almost finished with my third run through RE2 (which convinced me to go back and beat RE7 as well as the RE1 remake), so now I'm going to need something new to play. Hearing about FF9 makes me wanna go back and finally finish the thing.
I'm also in the market for a good survival horror game but I don't know that there's many I haven't played at this point.
PSP and PS3 have the original game available if you have they (I would prefer the remaster though).
If you didn't play Alien Isolation and Evil Within are quite good. They have the fell of survival.. you don't have much ammo, you shouldn't fight much, you have to escape and survive. And in Alien you have that Nemesis fell, but on an enemy you can't kill and can kill you with a single hit, you really need to stay focused and hidden.
