2spec for old times sakes then battlescape came along and gave us a new era, and eventually leading up to it's down fall. innovationx revolutionized spawn pking, Revolution530 had ton of potential but never made that much of an impact. Runenova/Telos only a few know why this server took over the ps scene, leading up to corruptionx2 and eventually alotic.
I'm not a big fan of trying every server, just the ones who looked decent enough and contained quality. best would have to be corruptionx in terms of content, runenova for pking, and offcourse battlescape for overall.
