There are very few JRPGs that I like, so I haven't given Resonance of Fate a shot. I'm tempted to though, because it looks like a good game.
My favorite RPG of the generation would be Mass Effect 3 though.
Well Resonance of Fate is better than Mass Effect because the gameplay is more challenging and not a cakewalk, you can control all members of your party, the characters have more personality and humor, less talking, more action (not a conversation simulator that results in....nothing), it relies more on strategy instead of just run and gun pew pew and it wasn't inundated with a controversial ending that pissed fans off as well as shady DLC practices...
This is subjective. I'm entitled to my opinion, as are you.
