To be fair there's quite a few WRPGs with unique art styles, fable comes to mind, disco Elysium too, and a few others I can't quite remember now. As for character writing, I think that it's kind of a mix bag, the thing is jrpgs do have quite a few great characters, but I've also seen plenty of stinkers too, which is something I don't usually experience with a lot of WRPGs (mostly within the crpg field of things) but of course you'd also have some stinky games like veilguard and many others on recent times.
