User blog comment:Imrlybord7/TAR-21 vs UMP/@comment-1681465-20100330115636

I prefer the UMP as well. I've recently finished 9th Prestige and Lightweight, using a UMP w/Silencer throughout and it has proved to be very effective. I've beaten snipers with the UMP with controlled 2 shot bursts, 2 short bursts at distance and they are down. The light nature of the UMP allowed me to flank entire teams on the likes of Wasteland, something which a TAR-21 would take longer to do. I mean i've now had over 500 headshots with the UMP and nearly got 2500 kills with the TAR and aim-down sights time is pretty vital in some situations. Combined with Lightweight Pro, i'd got so many kills by very small margins, something again the TAR could not have done.

IMO, the UMP is better and is a weapon more suited to general MW2 play.
