Only what I addressed. Typography, which you can disable or override easily.

Let's be clear, Bootstrap is the most popular CSS framework in the world, whose Github issue threads have been pored over many times more than Blaze's are likely to be for a very long time, and Bootstrap 3 at least never took any power away.

There are some really cool looking elements to Blaze and I'm very interested in using it for some upcoming projects, but to infer that you should ditch Bootstrap for it, on the basis of opt-in vs opt-out is very misleading.
