What I think Linux is missing is a good "first intention" debugger.
rr is great, I have used it a few times with great success, but always as a heavyweight, for solving really tricky bugs. Usually, printf is first, then gdb and/or valgrind, then rr.
On Visual Studio (which has a great debugger), the debugger is the first tool I reach. It is simply more convenient, more reliable on a day-to-day basis, plus, there is "edit and continue". Generally I prefer the Linux dev tools (rr is one of the good ones, I also love valgrind), but for interactive debugging, for me, Windows wins.
