I've never had any trouble with any HK, Sig, or Glock I've ever owned so it would be hard to say that one was better than the other (for me). That said, I did like the grip design on the Sigs more than the HKs and Glocks (but still not that much difference). But that doesn't make them "better". As far as reputation on quality, it generally lines up as HK, Sig, & Glock (first to last and still debatable on the order). But that's not a fair line-up. Try them all and see which one you like and shoot the best. Certainly don't buy one based on what I or anyone else on the internet likes. Remember, internet opinions are only hearsay, opinons, lies, boasts, bullshit, etc., etc.
