When I got started into guns (2009-ish) it was really the best option, XDs had just come out and I didn't like the ergonomics/bore height and silly pressed in extractor. So glock 19 it was. I took all my training classes with glocks, bought a crapload of mags (like 60+), parts, sights, holsters, barrels etc. Now it's too hard to change, both because of the re-training and also because of all the spares, accessories etc. I have for the platform. The guns and mags are also very competitive price-wise, and mags are much cheaper than sig (I have probably 40 mags I paid less than 20 dollars each for). I was in NC at that time and am about to move back in a few months so it doesn't matter much to me any more, but pre-bans are also fairly easy to find if you're stuck in MA. If I were to start again and price was no option I would probably go with something else. I shoot several other guns better than glock, but not better enough to justify spending the money to change platforms.
