Unreal vs. Unity Opinion
Unreal vs. Unity is pretty much the 'spaces vs. tabs' or the 'emacs vs. vim' debate at this point. Nobody who makes a living from gamedev is dropping their engine of choice thanks to a flashy demo or even a killer feature unless they're facing some kind of existential threat. Thus, the most knowledgeable folks can't fairly compare the engines, and the only people really making noise in this debate are amateurs with little to no skin in the game.There are exceptions, such as where a studio that made the switch for reason X or reason Y is able to clearly articulate what they're doing and why, but these exceptions only serve to prove the rule since they're extremely rare to come across.
