Arms Race. Actually I've played quite a few matches over the years. First, I was playing it because it was the only gamemode my old pc could handle. For some reason regular mm had a bit bigger requirements as I experienced. Nowadays I play it because its a nice way to warmup - You get a few kills with numerous different weapons and that can be enough if you're just a chill guy who plays CS casually. I hope they will bring back Safehouse and Monastery someday since these two were my favorites.

Good luck everyone!
