My friends and I play it pretty regularly, we use Balanced Annihilation. If you ever played Total Annihilation you should fit right in.
I haven't really played much of Evolution RTS, it doesn't really appeal to me that much. It's kind of a re-imagining of Total Annihilation where there aren't different factions or tiers, there are just a crap ton of different kinds of factories.
So like Air Factory, Kbot Factory, Mech Factory, Invis Kbot Factory, Vehicle Factory, Hovercraft Factory, Ship Factory, etc. - that all have their own strengths and weaknesses.
I can't comment that much on it but I can definitely vouch for BA, it's a wonderful game to play, especially with friends.
