I bought the colt version. When I was looking I had the colt and s&w side by side to compare. The colt seemed like it was a better rifle to me. I didnt like the s&w mainly because it was almost all plastic. That and the fact that the stock and reciever was one piece. The colt just felt like a better quality rifle (if you can deal with a wobbly stock).
Shooting it, I didnt like it. It was fairly accurate but you had to adjust the bolt speed for different kinds of ammo. Also, dont even think about running remmington ammo through it as it would jam on every other round. It reminded me af a typical AR, very finiky, which is why I sold it.
The colt guys will say the colt is the best and the s&w guys will say the s&w is the best. If I were you, buy a dedicated 22 AR upper to put on a lower or buy a gsg-5. I love my gsg-5 and regret selling one of them for the colt. A far better option.
