Mine was a semi-impulse buy. A "I wants it, and I'm gonna have it kinda thing." I couldn't find anything that was really doing it for me online, because a lot of people were still pushing out the old duty models and none of the new ones. Not to mention my local FFL's would charge 40 or even more depending on who it was. In the Chattanooga and NW GA. area there isn't a single place that carries CZ, unless its the shotguns. Which the whole thing is made more convoluted by the fact I'm a buy what I can feel person.
I will say that I have a shop around here part of a larger network where I can get 75's and such relatively cheap, but they're ordered online. I care less with the 75, cause its not like there is anything too terribly new about any of it.
As far as the G19 comparisson, I prefer mine over a G19. I mean, the Glock is solid, I personally just can't get behind the ergos of it. I have a oddly long thumb on a normal/small hand for somebody my size, and it just kinda messes with the grip on most things, but thankfully not any of the CZ's I've held.
