I've finished WoFF and am currently playing Berseria. I personally prefer Berseria so far, but they're both good games.

What are some things you like about the Tales series and what are you looking for in specific?

WoFF has a lot more in the way of sidequesting so far, collecting Mirages. It's got some classic FF callbacks and characters. It's cute and generally more lighthearted and fun. Some decent customization options. The story isn't bad but isn't really the central focus, although it gets more engaging later on in the game.

Tales of Berseria has an engaging battle system, some really interesting characters, a good group dynamic (as usual). The story is the central focus and it's a good one. The story is a bit darker than typical Tales games, focusing on a group of anti-heroes fighting what's considered the "good guys" which is an interesting take on things. It's got cooking again and eventually you can send a ship out to scout for treasures. The ability system is FFIXesque where you learn through equipment.
