PVP FUN= Matrix Online. best game for pvp. 1v1, 10v10 whatever, u name it. there was no safe zone besides the Loading screen(jack in zone)
PVP SKILL= Global Agenda. AvA Agency vs Agency= 10vs10. u got snipers, medics, assaullts, and robotics. really fun and takes tons of skill and practice to get really good.
PVP MASS KILLING= 2Moons. Love this game cause i would go out to a map and kill 300+ ppl all different ppl, haha and if u PKd lowbies u got penalized for it, and if a higher lvl killed u while u had a bounty, u went to jail. i spend 3 days in jail. and u cant logg off 3 days....no no. u have to be logged in for 3 full days in jail, cause i had a super high bounty, haha
PVP Better Gear=Better Toon no matter the skill= RF Online. F2P w a Cash Shop game, so the richest person wins. but from 1-50 if its a fresh server. its so much fun..
those are just my top choices, i didnt not care to read the 1 billion pages, haha sorry:)
