The UE4/PS4 version looks to plastic with the combination of ~realistic~ graphics and the art-style/design of the characters, they look like dolls. The way the camera is also set-up in battle (from what they showed) and the nigh-frozen character models just makes it look fake and lifeless. The cutscenes look better but the actual gameplay looks bland as all hell if you ignore the "ooh aah HD"ness of it which is a skin deep cheap aesthetic that does nothing for me.
I'd prefer the 3DS version but, then, I will be importing the 3DS versions so I am unlikely to buy it again, so that puts me in quite the pickle on what I'd want on a hypothetical Switch version!
Maybe I just don't care and won't buy it. /shrug
