Didn't read all 8 pages... but presently I've got three CZ 452's (had 3 or 4 others over time) and one Ruger American (had an unthreaded version in the past).
The CZ's are nice, accurate, the triggers need work, something You can do on the cheap or else buy a new sear or a complete trigger. The magazines, especially the metal ones are excellent (better than most). I dislike their fire to the rear safety, but have gotten used to it,
The Ruger American; Very close but not quite as accurate as the CZ's. I actually like the stock for offhand shooting, well thought out even though it does not compare to a nice wood stock. Big Plus is that it uses 10-22 (including the 25 rounders) or 77-22 magazines which are affordable and everywhere, also they are flush fitting unlike CZ's. If the stock puts You off, Ruger just came out with a 'target' version with a laminated wood stock and a heavier barrel profile (0.835" or thereabouts).
