Which is better, US Amps/RE Audio or Sundown Audio?

I'm looking for a few suggestions on these brand choices as my new sound system set up I will try my chances on. I've went through too many main stream brands like kicker, mtx, hifonics, fosgate, soundstream, etc. Never wasted my money on sony, pioneer, kenwood, or any junk like that (only head units from those guys, lol). Alpine type x was alright but wasn't what I really expected. Anyways, I've heard good things about these companies and want just a few opinions before I just chose one cuz I'm kinda digging RE audio becuz their appearance is just more eye appealing but I don't want to just make my choice on that alone, ha. If you have other brands u may suggest, please feel free to say any that comes to mind. Thanks in advance.
