Pros:

Visually awesome
Medium sized
Gameplay is solid
No bugs found

Cons:

Didn't see a loading screen, just a generic one, but not a big deal.

Conclusion:

I did not play the Source version, so I will only speak to this version, which is great.

Pros:

Very balanced layout

Cons:

Looks just like Source version, which was a bit plan even for that game.

Conclusion:

I know people love CS for the gameplay, but I like to see some visuals as well, and this is just a kind of too plain for my taste. However, the gameplay is perfect.
