I get that you want to go with raptr, and I get what you're saying about its chat interface looking "cleaner" than the others. But you're completely discounting that there's a whole other part/interface to raptr - the part that has the video stuff, the game optimization stuff, the game library stuff, and all the AMD-centric driver stuff. It's overall cleanness factor is therefore dirty as sin. Evolve may have a game ad at the bottom, and I sure as hell don't like that, but that screen is pretty much it. None of the other stuff. So it, relatively speaking, is squeaky clean.
btw, I'm not voting for raptr with these comments. I'm still thinking a more universally adopted chat service, like Skype makes the most sense. But - alas - there are those who are venomously opposed to that, too. idk. Not really sure where this is going...
