Not quite the same but I have a 19 and a 27. And, I carry the 19 almost exclusively. The only time I carry the 27 is when I am really worried about printing although I have to say I don't think I have ever been made while carrying the 19 (or any gun). Also, the 27 is a little snappy to shoot. I have g22 as well that is a lot easier to shoot than the 27 so I imagine the 23 would be in between. You can't go wrong with either but if you are going to be doing a lot of shooting with it, I would suggest the 23 over the 27.
Hope this helps.
