I haven't. Thanks for mentioning it. However, after briefly looking at its website I can't see what functionality other than source code search it has that tui lacks (tui is built into gdb - unless compiled without)? Tui looks very similar to the screenshot shown on cgdb's webpage. I too use gdb mostly with embedded devices (over swd with openocd). I like to have at least 3 windows with source code, disassembly and memory/variables/watches.
