Most people know that LIVE has the advantage over PSN as its been around longer, although PSN is catching up very quickly and if not on par with LIVE. Its just friends on LIVE with a PS3 aswell say that they notice more "lag", however they are probably fanboys. I cant say anything myself as i havent played online on a PS3.
The HOME thing thats coming to PSN looks sweet though. Although this wont affect the online gameplay.
