...would you guys recommend from the two? Now i've upgraded my PS3's HD (640GB), I finally have space for stuff again.

i would say there are alot more people playing decimation.
anyone that bought both of them are more than likely playing the new maps.
the FY71 gun, 5 maps instead of 4 and the latest patch could have edged people towards buying decimation, even if they didnt buy retaliation.
i like both packs but decimation pack is better imo.

Thanks for the reply, i've just noticed the other thread on it as well so I think i'll definately be getting Decimation now. I just need something to add a bit more variety.
