CZ. Excellent CS, excellent value, excellent little rifle. Trust me, I have experienced the goodness that is CZ.
Trust me, I did this exact same comparison earlier this year. I decided on the CZ, took the chance and ordered it without ever seeing one in person. Without ever having a chance to see how the "humpback" stock worked. Well, I can say it's a phenomenal rifle.
I was looking for a rifle to replicate the handling, smoothness, and quality of my old Winchester 69. Guess what? I found it and knew it the first time I threw the CZ to my shoulder. It's like a frickin' laser beam.
I'd get a CZ-452 Trainer in .22LR for the range gun, and pick up an inexpensive used Savage or Marlin in .22Mag or .17HMR for the woodchuck whacker.
Do it right and you may score two rifles for the price of one...
