As for not needing to check one's buddy's po2, maybe it's because my budyy is so commonly my wife that I feel compelled but on the other hand it seems to me that CCR diving is more of a buddy sport than OC and occasionally checking in with one's buddy on po2 is on par with being aware of one's buddy's remaining air supply on OC...
There is the difference. You do recreational dives with people whom you have to take care of, and I would never do technical dives with one that I have to double check on a regular basis. And the only recreational dives I do are when I teach.
There is nothing wrong with either way, just what you want to chose.
