By everything it sounds like you mean HD/SD/CC. I see it this way; if it's a functional tool you're looking for, Glock is a great choice. Beyond the shootability etc, there are upgrades and spare parts everywhere for it. And many experienced people select it as their sidearm when they have a choice. That doesn't mean you should because you're not them, but it does speak to what a great tool it is.
If you live in a 10 round limited state or think you might be anytime in the near future or you want to be able look at the pistol in 20 years, be in awe of it's classic lines and you still want a viable HD/SD/CC tool, I would personally choose a good 1911 or maybe even a K frame revolver. Glock is a great tool, no doubt about that; but, it still looks like a Glock. And no one is going to be any more in awe of the classic lines of that pistol in 20 years than they are now.
My point is that it depends on what you're looking for. I personally don't subscribe to the buy three of one kind of gun and stick with it philosophy. I understand the concept, but for me, it's just boring as hell. Being able to shoot different platforms in different calibers is part of what keeps me interested. And it gives me exposure to the different workings of different pistols. For me being engaged in the activity of shooting and being 85% proficient with different calibers and platforms is a better choice than being 100% invested in one platform or caliber. But that's me and not you. Whichever direction you choose, make sure you enjoy it. Because that's what will keep you engaged in the activity over the long run.
