Keep in mind that gates will not remove that noise from a track with vocals for example. They can remove the noise when the singer is not singing, but not while the singer is actually singing. Gates are on/off type devices. They do not remove certain sounds (unless you are talking frequency ranges), but remove all sound. This means you can not pull birds chirping out of a vocal take except between passages.
That being said, the Behringer gates are on of the few pieces of Behringer where you actually get a half way decent product in my opinoin. They have plenty of features, but they do still have that trademark Behringer sound (you know, the what happened to my frequencies above 10k and below 100hz? thing...). Currently owning gates by Behringer, BSS, and DBX (the nicer 1074 gates, not the crappy project series), as well as once owning Drawmer and Klark Teknik, I can feel confident saying that the BSS and Drawmer gates sound MUCH better than the Behringers. The seem to be more natural in their opening and closing, and are much easier to set usable thresholds on. The KT and the DBX I still like more than the Behringer as well, but I do have some Behringer gates in some of my live racks still. They allow me to add a higher gate count at less expense. I just can't afford BSS and Drawmer in all 6 sets of FOH racks and monitor racks.
