I have an SR22 as others have mentioned above, fun plinker. I got it before they came out with the longer barrel version, which I'd probably get if I were buying a 22 pistol now.
However, since then, I've gotten a bunch of Glocks, including a 19, so If I were shopping now, I'd probably be getting the G44.
Like others have mentioned, the biggest reason to go with one over the other would be if you wanted to match a specific manual of arms with another pistol.
