GDB (I don't use LLDB) is fully programmable and has multiple user interfaces (TUI, Emacs, DDD, graphical frontends and various .gdbinit configurations that emulate SoftICE L&F).

It's a power tool and takes some time and effort to learn and master. Superficially dismissing it / wasting your time with something that in all likelihood will end up going nowhere while lacking most features that make GDB great, does not a good recommendation make.

At least you'll probably learn a thing or two while you implement it, but I'd rather not waste my time using it.
