I've never actually worked with Unity so I don't have first hand experience of its features, but I wouldn't say it's a shite engine.

Currently UE4 is the go to next gen engine because of it's graphical capabilities. It looks outstanding, and of course it's free so everyone has it at their fingertips.

Although Unity doesn't reach the graphical capabilities of UE4, it shouldn't be disregarded. It's a very powerful engine for creating specific types of games, especially for the mobile market. It just works well in terms of actual game design.
