I have to admit I do also have a lot of crashing going on. Sometimes it works fine all along, sometimes it will repeatadly crash while doing basic editor stuff. Creating variables, importing textures and so on.
I even made a post for it and if someone has any idea what could help I would be very glad.
If never tried other engines, but I think unreal is quite easy to get in and do something. There are some pretty good games that use unreal as well, so it seems to not to bad?
Maybe the documentation could be better. But otherwise you get everything you need to start a project, from models to plugins which really is work which is already done for you.
