Well in some areas it sort of looks ok on Switch and then the second after it looks like a rushed Vita port. I'm really conflicted on this. They made a pretty bad decision porting the Vita version and not the PS4 since it's pretty clear they could have made it look better. They removed way to many particle effects and blood / speed effects, it really hurts when it's shown next to the PS4 version.
I'm kind of annoyed that Tecmo Koei seems to consider the Switch as a rushed portable port machine. FE was hold back because it was essentially a 3ds game and this is the same because it's basically a Vita game. When are we getting a REAL Switch game Koei ? Yeah they've got sh*tloads of support for the system but the fact is I still haven't gotten a single one of their games even when I was planning to :/
