I use Unreal in my day job and I am very familiar with it, and I found it much more difficult to learn and operate than Unity.

Even as an Unreal "expert", for personal projects I still use Unity, it is just much easier to get stuff up and running and iterate.

I found Unity to be easier to start with but led to a lot of garbage.

Unreal has a steeper initial learning curve but the system itself is more pleasant and the built in components are much more helpful. I switched to unreal after a couple years of Unity and strongly advocate others to do the same.

Definitely Unity.
