This may have changed, but, at the time of writing, rr was tied to the terminal gdb interface, which many people understandably don't like to use (i.e. not what they mean by "decent"), preferring the more direct connection to their code of a visual debugger like VS.

That said, rr is amazing and I strongly encourage people with an aversion to gdb to suffer through the text interface (if they don't have access to some visual record/replay debugger, of course).
