Based on what I've seen of the recent CZ550's and the Rem 798's, and handling both, I'd take the CZ over the Remington, even at twice the price. CZ quality is going up, Remington is going down, IMHO. I bought my first 550 a couple of months ago and have been exceedingly pleased with it.
As a matter of fact, I'd take the CZ over the Win 70 .375's that I've seen, that were built in the last 5 or 6 years.
