For what I do I really like A/C. I don't take any of the gov insurance (medicare, caid, or tricare) so the MU stuff is useless to me. Even if I did take those I probably would not take the government $ because I opposed the stimulus and feel like I would be stealing if I did because in my mind all taxation is legalized theft.
I probably would have kept the billing inhouse if there was a PM/billing portion with it, but since it didn't have one, I just scan my superbill and ftp it to a billing company who takes 7% of what they collect, so overall I would choose AC again.
