Actually, DWARF based profiling isn't very good, which is why so few people do it. It's slow, it's memory intensive, thus the sampling capability is much poorer.

That's an oversimplification. It's certainly slower and generates larger profiles, but it's also much more powerful. You can see inlined functions and get an association to source code lines in the annotation. Sometimes knowing the function names is enough, but especially in a larger code base or if you're not so familiar with the code that you can match assembly with source lines manually, this can be enormously helpful. For my part, I prefer DWARF profiling when I have the debug info around.
