I actually did a status match last December... from AA Plat to CO Gold. I must say it's been better with CO so far, the fact that you don't have to pay to get upgraded (ala stickers from AA) is a big plus for me.

Another story is the likelyhood of getting updgraded. Out of EWR is kinda difficult, specially on routes like ATL, LAX, SFO or transcons in general. But Florida routes have been easy, which is where I fly the most. So take into account where you are flying in and out of to see how likely you'll be updgraded.

BTW, I do find CO's forum much more friendly! ^
