I use Git LFS with my Unity projects. Other systems exist, like Plastic SCM, but their much much harder to use. I had issues with a contractor who couldn't figure it out and it partially lead to us abandoning that version of the project ( on v3 now, had to change direction though). Unreal is significantly harder than Unity, unless you stick to blueprints. Unreal's C++ is a harder language than Unity's C#. Plus I find Unity's community to be much more newbie friendly. Unreal tends to heavily tilt towards massive projects. Unity treats mobile as a first class citizen and it's very easy to get started. Then again, I've been using Unity since 2012 roughly, had I started with Unreal I might have a different opinion.
