More nice vs Nicer

Aniki, wouldn’t that be more nice, if you interact with that little fuzzy fox more?  What?? What am I supposed to do, where am I, who am I actually??? No one seems to know, nor do I. Don’t get too serious, what I’m saying is just some random yet wild thoughts floating up in my mind. By the way, more nice vs nicer, which one’s correct to use? It seems to be a long time debate even between native speakers. But I’m more used to the former anyway.
