cs_office: I played this on CS 1.6, but I prefer the CS2D one. It's perfect for tactical FoW gaming! Second favourite! cs_assault: I really dislike it. Although I like hostage rescue, this map doesn't "heat me up". de_dust2: I think it's pretty good for Construction game mode, most people disagree and tell it's Standard mode-exclusive. de_dust: Just like dust2, but this one I strongly recommend Strandard. de_cs2d : my favourite map! It's perfect for my favourite weapons: AWP and M3. Most people dislike it because it's a bit hard to survive in such small-spaced map with M3ers and Snipers everywhere. You must reach a certain level a skill to survive here. Since I reached that skill (I rarely play CS2D now, but there was some times I was totally obsessed with it) I was able to partially master it. I give credits to <fruitpapje> for maintaining their awesome de_cs2d server with no AWP-restrictions, mostly lagfree and has quite friendly admins.
i'll go for de_dust2 deffinitely, its big enough for many diverse tactics, fow and no fow gaming and pretty cool with ff on, its beastly to play that map 3x3 or 4x4, pure ownage, love it
I luv all maps but DC MUST CHANGE HIS CS_ASSAULT_SHIT MAP TO NORMAL!
de_cs2d: very fast and nervous map x_x
de_dust: all fights in center. Need some changes too.
de_dust2: bug hign-strategic map for 5x5 or 16x16 fights
cs_office: need some changes too, but this map is good.
de_dust1 & cs_druglab are my favorite picks back in the day. as_plane was also cool because of the walking on air / invisible panels at the CT's spawn.
Well I used to play de_cs2d a lot, actually almost only, but then I got pretty bored of it and started playing more in other maps - of which de_dust2 is definitely the best. I virtually never play cs_assault, for I have a very dark screen on which I can't distinguish Counter Terrorists from the background (I should get a better screen indeed...). I want to play more cs_office, but I never see people playing there :(. And for de_dust I agree with FlooD.
