The ANTS sight is very nice. I'd say they are as good as the sure-locs and maybe more durable. The scope mount is a little more difficult to setup than the sure-loc but not really that bad. These things are tight. When you first get them it's kinda difficult to move the slide. But after a couple weeks of use, it moves nicely. This is one advantage over the sure-loc, less slop.
There are quite a few good scopes out there. It would depend on your budget. I like the larger diameter scopes for 3D. 1.5" or larger. So that gives you Bullseye, Extreme, Sureloc, and many others. Sureloc is the nicest I've seen lately but it is also the most expensive.
