After a little thought, I reached a fairly astounding conclusion - both guns are made by CZ. I hadn't thought that the case, and I wish it wasn't, because I like buying American.
For rifles, the CZ 452 Lux: perfectly balanced, good sights that line up perfectly for my build every time, and a stock rake which is well suited for my build. An SKS with a stock extension pad comes in close after that, but I think that might be due to the frequency of shooting it - same for my AR15.
For pistols, the CZ75/CZ75B. Sits low in the hand, the length of pull (do pistols have LOP?) is perfect for my finger length, the length of the grip is sufficient that even with a sloppy grip the grip is still firm with no fingers or part of my hand hanging off the bottom, and the weight (being an all-metal gun) is balanced with or without a loaded magazine. BHPs and 1911s come in after that.
