Winchester by double the votes, tried (Federal, Winchester and Remington) in .223 in both virgin/new and once fired in my many rounds of reloading .223, the others aren't close to Winchster, Lapua however, is the BOMB!
I said Remington, because I had some limited exposure with both and you only gave two choices. I had to withdraw from competition due to fired primers coming out of virgin Winchester brass and falling into my lower locking my trigger twice. I have not had issues with Remington.
I have used both without any problem at all, but on another website I frequent that is more specific for reloaders, there are a lot of reports of problems lately with Winchester brass in several different rifle calibers.
I have a bunch of once fired stuff that needs to be processed, and didn't feel like doing that today. So, I'm just going to buy 50 cases new to load some new loads and shoot for groups and chrono tomorrow, I bought the Winchester

A few years back I decided to check the consistencies of unfired brass from Lapua, Federal, Winchester & Remington.
I had 100 cases of each. I checked for Weight, Neck thickness & overall uniformity.
Lapua was the best, very consistant.
Followed by Federal Gold Metal brass. Very good. (No longer made)
Winchester was ok. Good pratice brass. (I love their pistol brass, before they started screwing with the flashholes, now ya have to sort that as well.)
Remington was crap. Very inconsistant weights over a wide weight range. Some off center flashholes
This was about 10 - 15 years ago. Things may have changed.
I normally sort my brass to +/- .05 grains, after necks are turned.
