Joe_Kidd, you won't regret either purchase.
I speak from experience. I owned a CZ 452 a couple of years ago.
One of the finest .22 rifles I've ever shot. Tack driver. Well-built. Smooth cycle.
I sold it
only because I realized that I'm not a bolt action guy.
(That was the first bolt I've ever owned. Just didn't work for my needs.)
I replaced it with a 39A. Even though I've not shot it as much as I want to yet (long story about why), I'm just in love with it. It's well built, close enough to tack driver for me, cycles fast, carries well, a little bit of history. (For several reasons that need not be discussed here, I'm thinking of having the barrel cut down a few inches to carbine length. [Yes, folks, I'm aware of 39M, but I have my reasons for cutting down a 39A, so please save your arguments.
])
So, like I said, you can't go wrong with one of each, and if you eventually decide you only want one, you're still golden.
