I'm a music teacher and when parents come to me asking "which ____________ (insert saxophone, clarinet, etc) should we buy for little Susie" I always tell them to decide approximately how much money they want to spend and then compare various models of instruments at that price point. For instance....Selmer saxophones are excellent. But so are Yamaha and Yanagisawa. They have differerent timbral characteristics and fairly significant differences in the key layout/feel. Is one inherently superior to the other? Depends on what model you already own I suppose
As far as guns go, you are going to see different price structures amongst different manufacturers. SIG and HK are on the high end of the 9mm from the major manufacturers while CZ is on the lower end (not in quality...just price). If you say to yourself, "self....I can only spend $450 on a 9mm handgun"....then stay away from the pricey guns and focus on the reputable companies in the price range you've established.
All of the firearms listed above will serve you well....but they differ radically in how they operate, their size/weight, construction, feel, etc. A Glock is radically different in all of the above characteristics from, say, a CZ 75 or Sig. But, it is a close cousin to the Springfield XD.
Are some of the listed guns inherently more accurate or reliable? I guess it depends on what you already own
FWIW, I have an HK USP 9f that has been 100% reliable over the course of 3000 rounds, but I don't feel that I'm as accurate with it as I am with other 9mm guns. Not the gun's fault....rather, it's the funky trigger pull that amplifies my still developing technique.
