I have this UTG on my Bobcat and am extremely pleased with it. I will buy an atlas someday just to compare, but this has been money well spent so far. Quick release, very sturdy and has some side to side moment, not sloppy but very controlled.
I have always used Harris bipods, but then I got cheap and bought a chinese clone. The chinese ripoff had many problems and became unusable after 6 months. I'm back to buying Harris bipods.
I'd say to go with a Harris. It's easy to use and install. I've had UTG, Harris, and Atlas on my rifles. I think you get the best bang for your buck with Harris.
