Lots of opinions. May I suggest you go to a range that has rental guns available and try various kinds. Or, if you know friends with different kinds, see if they will let you shoot them. What works for me, won't necessarily work for you.
Glocks are accurate and reliable, I once owned one, but it didn't fit my hand well and I was nervous about the trigger. I carried it a couple of years, then traded it.
Different strokes for different folks.
