shouldi buy the m9

Hi everyone, iam looking forward to buying the m9 soon, it is going to be the AT&T version. Usually in the ATT forums on xda there are many different threads almost everyday, but in the case of the htc one m9 there are hardly any new threads. Mostly the development threads are empty. So my question is, is there something i should know, like everyone converting to an unlocked m9 and discussing threads in this specific m9 forum? if no one is converting and there are no ATT threads then it would be rather pointless to get the ATT m9, i might as well buy the galaxy s6
