Which is better cod4 or cod5

CANNABLECATFISH_IICOD5 has better graghics, sound, the single player is longer, more veriaty of levels, more intence single player, much more multiplayer options like co-op online and split screen, more online games like capture the flag,NAZIE ZOMBIES! better weapons, larger maps, tanks, more mp maps, more regular updates (more maps and less hackers).

OP- now that I've played both, i like cod4 campaign better, but cod4 online sucks. Cod5 online is the funnest thing ever, and nazi zombies is just disturbing.
i agree cod5s online is fantastic if not the best online game so far if you are looking to buy one of theese plastation games i would avise you to get the call of duty 5 world at war for plastation 3.
