I would suggest UE4. 
Here are my reasons!
UE4 is free!!!
Blueprints! I can’t program! And now I can make games!
Easy workflow. Once you get into it, you will never want to go back!
Did I mention it is free!
Once again… ITS FREE!! (As you can see I’m still excited about that!)
And look through all the other posts! they list everything great about it!
And deepstar, just read the F.A.Q. at the top of the forum. Also welcome to UE4.
