After you get over the idea that when you walk up to the lake, the waters will part if you're carrying a Glock, you can get realistic.
I've never found a Glock that fit my hand, and working in a gun store, I've got as many used Glocks as any other gun... so they aren't the panacea that the cultists dream them to be. They're just another brand of gun.
I have customers that come in who won't have anything else, and customers that won't have one as a gift... so there's no "one answer" to this question. I also have Kimber buyers who don't think anybody else makes 1911's... and they're just as wrong as the Glockies...
I've got 52 different pistols of my own, and none of them are Glocks or Kimbers... and it's not because of cost... I've got some expensive guns, and some cheap ones. I've just never found either one of those brands to be a value for me, and I've never found one that fit my hand and that I couldn't put down.
There are good guns of almost any brand out there, and junk by some of the most expensive manufacturers... you have to field test a lot of guns to figure out when you're getting the sales hype, and when you're getting quality products. I don't gage my opinions based on how much guns cost or how popular they are... I look at the manufacturing quality, how they "run", how tight the guns are when they're used some, and a lot of other "little" things that are clues to what kind of quality is in the firearm.
You can spend a thousand bucks on a new Springfield, or a hundred on a Hi Point... and they will both make the same bullet go bang... One, will have much better manufacturing features, and the other one will look like a boat anchor... but there's still a market for both of them. How you fit in, and where you fit into the "extremes" of the price selections will determine what your gun collection looks like.
I've got several of the new polymer guns, and a lot of the old steel guns... and how they shoot individually determines a lot of what I think of them. Being a Glock doesn't necessarily make a gun "the one for you"... it has to fit your hand, function correctly, and be what you consider a value for the money.
For "Glockies", there's no other gun... for me, they need to make one that fits my hand to have a chance, and in a caliber that I'd want to use for self defense.
