I think they all have their merits, but I think I have the most fun playing Survival. Not gonna lie though, sometimes I just want to lure pandas to my home base without being accosted by monsters, so I sometimes change it to peaceful mode. Most of the time I do enjoy fighting monsters, just maybe not when I have two dumbass bears following me at a snail's pace. If I really want to build something and don't feel like actually mining or crafting, I'll play a creative game.
