Very difficult question, i would say Ruger auto pistols for striker fired guns, for overall reliability, accuracy, and toughness. Gen 3 glocks are top notch as well. You also have all these 1911 makers, who can build an exceptional pistol that lasts a long time, is very accurate and very reliable. So the question to this answer does not exist. I think SIG is out of this one, their current product is not even close to what it used to be. Chipping and galling of frames, bad customer service examples, on top of poor performance in torture tests i have seen, via youtube. Some HK pistols are now made stateside, and very good handguns they are
