It is just one of those things, RA is like a huge emulation operating system that does it all where BH is an attempt to make an all in one emulator. There are problems with that so RA decided to make it modular. With RA you just need to set it all up and the best way to do that is to watch the youtub how to set up RA stuff. The setup IMO is not all that confusing because there are auto find game tools built in, you just need to do work before you play it. Once done,

It comes down to this. You either want it simple and hope things work, or are wiling to learn a bit and make it all work. RA is a tool that will setup your controller, your roms, your emulators, and all the images in a nice little front end that in the end is a point and click tool to play a game. Ever second that goes by RA is being worked on by a team of over 200 developers. Where BH may get updated once every year (if it is even still updated).
