It's amazing. I'm personally still a huge fan of the DS's dual-screen battle complexities, though I do recall that was a major complaint for some people. Solo Remix, the mobile port, changes the combat system to be a lot easier, and Final Remix, the Switch port, I think changes it even more to be better suited with Joy-Cons.
Final Remix is on sale right now for $25. It's supposed to have extra content, so it's probably the best edition. I might even pick it up myself again to see the new stuff.
The story is by Nomura... and does feature a lot of traditional JRPG tropes... But boy is it also fresh, extremely cohesive, and it has a ton of great character development, even for minor characters. And the music is boppin'.
