I own both as well. I love them both equally and each has its pros and cons.
For the CZ-52 I love the way it looks, more stability when I shoot it offhand, simple disassembly, its classic European qualities to it, and the collector value in it (one country, 200,000 made compared to the TT-33 made by many countries in the millions). I see the CZ-52 more as a range toy/collector's piece.
The TT-33 on the other hand I love the better ergonomics, slide release, larger ejection port, and Colt 1903/1911 qualities to it making it familiar to me. It is one that I would take in a life or death situation hands down over the CZ. Plus the added safety, although butt-ugly, functions well on mine and when it is in use along with the hammer safety that trigger isn't moving period. I would conceal carry it if I could.
And as already noted many times the 7.62x25 is a fantastic, sweet round and at a bargain the cheapest ammo available next to .22lr.
