I just went through this last month. I've carried a G26 for years (backup and off duty for my PD job) and, overall, loved it. Many thousands of rounds with no trouble at all and I had compatibility with my other Glocks.
My only real problem was that the G26 was so thick. It shot very well, but didn't carry the best in the world sometimes for me. For example, for backup when on duty, I carry in a holster on my body armor under my weak arm. The G26 was so thick that it would rub on the inside of my upper arm and would tend to get somewhat uncomfortable by the end of my 10 hr shift. When carried off duty, it would occasionally print during the summer when wearing just a t-shirt.
Last month, I bought a S&W Shield in 9mm. Night and day difference in carrying between the Shield and G26. Although the Shield is pretty much the same length and height, the difference in the thickness is absolutely amazing. The Shield carries so much better than the G26 it is absolutely amazing. The Shield does not rub on my arm when on duty and it is so thin that it disappears under just a t-shirt when off duty. The trigger, on mine anyway, is very Glock-like, with a very distinct audible and tactile reset in just about the same place as my Glocks, making the transition easy. The trigger is a little heavier than my Glocks, but other than that it is very similar. On mine, the thumb safety is so stiff that I can't ever see it getting accidentally applied and causing an issue.
If I were you, I'd also include the Shield in what you are looking for. If it doesn't work for you when you get it in your hand, OK, but I'd at least hold and dry fire one and see. I can't say enough good about the Shield. S&W really hit a home run with the Shield and I can understand now why they were/are so hard to find. I really wasn't happy at first about another gun type/brand, different magazines, etc. But it had turned out to be really a non-issue and it works really well.
