I could give an exhaustive list of pros and cons, but they are, at the end of the day, based on personal preference. In short, however, I found the quality of the fit and finish on the CZ's better, no plastic, excellent triggers, super smooth actions, and usually MOA or better with most factory ammo--which is a huge factor for me. I also like the simplicity of the 557 series. I own three 557's and all are the same in overall quality and consistent in performance. I find the Tikka to be similar in performance (though I have had QC issues with them in the past) but they don't fit me as well, and while plastic has advantages and a place (eg. less parts to protect from moisture) it's not my first choice in a hunting rifle. The Turkish walnut on CZ's are a real bonus and great value, some being absolute lottery winners. Lastly, the synthetic stocks on the CZ's are also the best I've seen and used. I think if the CZ 557 were made in the US, they would be much more expensive. Yes, they're discontinued, but some dealers have some in stock. The short action carbines weigh a hair under 7 pounds, so they're not lightweights, but I have other rifles that fit that bill.
The new 600 series is a completely different rifle and I'm still trying to decide if they are right for me.
