If it's been a long time I recommend taking another look. TBF you can tell it hasn't had the millions of dollars of investment that the Microsoft debuggers have, but still it's come a long way over the last 5-10 years.

e.g. it now has decent multi-process support.

I agree MI is kinda horrid, but no need for it these days, you can do everything via the Python API, and the modern equivalent is Debug Adapter Protocol which GDB claims to support now (although I haven't tried).

There a million frontends, including both Visual Studio (via ssh) and VSCode, if you like those.

The perfect developer tool does not exist, but I believe that if you're debugging native code on Linux more than a few times per year then you should really know how to drive GDB. It won't always be the best tool for the job, but it often will be.
