Performance yes, you can't compete with that one because browsers don't let you control the low-level stuff. But the speed of development and the ease of doing complex layouts with css is hard to match (when you master css enough, of course), specially if you're trying to do UI from the code directly, without IDE helpers and visual builders.
The speed of development is very fast for the first 75%, and comes to a screeching halt for the last 25%. The web stack has no good way to answer basic questions like "does the user have arrow keys" or "what is the current mouse position." That's the point that you start to layer on the "hacks on hacks" that OP references.
