I have both the CZ and the Savage, though not the Savage you are looking at. They are two very different rifles.
The Savage is bigger and heavier than the CZ. They both ride bags well. Personally I think the CZ makes a better overall rifle but the Savage fits in better with the range. I could see carrying the 527 Varmint out in the field while the Savage is something I only want to shoot off a rest. The Varmint is pretty much done out of the box. The Savages have a ton of ability to be upgraded in about every way. There is a lot to say for the ability to swap barrels with just a wrench and a gauge. To me the CZ looks much better. My CZ will put 5 rounds under .4" at 100 yards if I do my part. I have heard of a lot of Savage guys stating theirs will hold that as well. I have been trying a lot of different loads on my Savage and am having troubles breaking much if any below 1 MOA. Luck of the draw I guess. When it comes to the triggers I can't see how the Savage holds a candle to them. I love the set trigger. I shoot with it very well. Some don't though. Even if you hate a set trigger the regular trigger can be set very crisp, light, and with very very minimal pre or post travel. Neither are bench rest quality but the CZ to me feels better, when set correctly. If left alone the factory has been known to set a bit of creep into the triggers which turns a few people away.
With how my two have gone I would pick my CZ over my Savage every day of the week. If I want to drop another $300 on a new barrel and $100 on a new trigger Im sure it could outshoot the CZ. That said I picked the CZ 527 Varmint up used for $400 which makes it hard to beat. My 527 in .223 will single shot load every time. The extractor has never failed to grab a round that was single loaded. I don't have the magazine insert either. I just lay a round on top of the magazine, push it most of the way into the chamber, and close the bolt. It pulls it out every time. Same with the Savage.
Many people love Savage rifles and I do too. I want to swap the one I have out to a 6br before too long. That was what I bought it for, a budget build with a fairly nonfactory chambered round. They are just two different rifles built for different things. I have the laminate version of the 527 varmint and wouldn't spend extra for a different stock. It rides bags very well and it saves a bit of money as well. Either rifle should be fine.
