In that respect, btrfs is so much better than block based raid1 because btrfs knows which copy is not corrupt.
Btrfs raid works on "file level" (extent level is more like it I guess), so on a 2 disk raid 1 the layout on one disk can be totally different from the other disk.
So as soon as BTRFS is really trustworthy stable, I will use it on bare disks, and scrap my md-raid. But for now md-raid is proven technology and fast too.
