I don't fear the command line. I just don't use gdb enough to know all its 
commands. I would need a cheat sheet in order to use it effectively from the 
command line. The extent of my command line use of gdb is limited to loading 
a core dump, loading the file with the symbol table and getting a backtrace.

I find it convenient to be able to watch the contents of multiple variables 
and easily dig through structures in GUI front-ends to gdb. I haven't gotten 
in to some of the other types of programming/issues you mentioned so ddd has 
been ok for me so far.

I read about a way to set up ddd for debugging of AVR microcontrollers using 
the AVR version of gdb but I haven't tried doing that yet. Using avr-gdb 
could get me into using gdb from the command line if I find I really need to 
use it.
