Are you just plugging to your PC or do you want to play from other sources like DVD/blueray player/tv/console etc?
Both are ok for PC. The Logitech is the better of the two, at least the main left and right are 2 way speakers, have no idea why they made the centre speaker different though. I don't think either are good for movies, so long as you aren't expecting too much from them. Theyre designed to be listened to at close range not in a family room.
