What are the advantages and disadvantages for the ps3 and 360?

[Ail]

For achievements I would say 360 has the edge by far right now as every 360 game has them.

However it's very easy to trade games saves and gain achievements for stuff you didn't do ( which is probably a reason Microsoft never awarded anything to people with high gamerscore as it's close to impossible to know if those scores are legits or not).

Trophies are lagging behind on PS3 but have the potential to not be so easy to hack so we can always hope that at some point Sony decide to reward players with high trophies count ( something like free downloadables arcade games make sense..)
