When it lags (when does it not?) Nuketown and Firing Range are two of the worst - it's like playing shipment - spawn, die, spawn, run 4 steps, die, spawn, die, repeat...
I prefer medium to larger maps because you actually have a half of a chance to use some strategy instead of all out firefight for the entire match. Allows you to have snipers, assault rifle & smg pairs or groups run together and cover each other. Smaller maps are basically a kill box that boosts whoever gets the position first because then it's spawn camping, especially on objective based games like CTF, Demo, etc.
