Input at this point is for anyone else shopping 
Based on looks alone, the CZ will always win. Supposed to be far easier to replace the barrels (CZ over Tikka) but that too is something I've never felt the need or desire to do. I've had 3-4 CZ452s over the years, only have one now. I picked-up a 457 Scout and put it into a 457 American stock=that's a fun gun I'm looking forward to some load testing with! (after the Yo Dave trigger, and after the snow)
Based on my experiences with these, and with the Tikka T1x (and a number of long-gone Savage rifles) ...if I suddenly had to start over and pick only 1 -$1000 .22LR bolt action, that would be an easy choice. Tikka T1x MTR with the 20" barrel.
