None of the above.
You lost “clean” when you said “mobile”.
Good sound is DEPENDANT on no veriables! In order to achive good sound everything has to remain as constant as possible. This is a struggle with permenent installations in clubs where the occupancy changes. LEss people can get echoy, most people can kill the mids. Etc.
It’s more important to have good components, a good board can make all the difference in the world. If you aren’t using active monitors then make sure your amps are of GOOD quality! The only processing I’ve ever used, aside from a delay to compensate for speaker distance and build presence is a BBE sonic Maximizer, unfortunately even though they produce good results, the quality of the internals is sub-par, so it’s a wash! Ohh, compression and limiting can be useful as well as EQing, but be careful you can get yourself in trouble (quality wise) pretty quick, the more stuff that can change on your setup, the easier it will be to get FAR FAR away from where you want to be. Best way to introduce a component is to center it out, so it has no affect, and make subtle changes, use it for a while, and when you get to where you feel it sounds best, then center it again and be prepared to be frustrated when you think it sounded better centered out. 
It’s an art, not a science.
