Wow thats a loaded question...s.
Both the 226 and the 75B are excellent weapons, The Hi power is a very good weapon too. I would make a list of the guns I want and include the ones you read bad things about because like I always tell my employees when they say "Oh I read it on the internet" I say "Oh God it must be true then" and give them the look.
Personally I would get the 75B before almost any gun out there bar none. But I am a pretty loyal CZ fan and have nothing but good luck with all my CZ's. That being said there are as many folks who have had years of nothing but great luck with Sigs or Berreta 92's or XDm's or Glocks or Ects.
A hand gun is personal and it is important it fits you and serves the purpose you need it for. Go to a gun store or a local range. Good Luck buy the best gun for you that you can afford. Foe me thats the CZ,
