Same for me. For example, I like using git gui or tortoisehg when doing complex commits as those tools enable me to find, inspect and select all necessary files faster than typing a command for each file/task. For examining recent log entries or switching branches, pushing etc., I prefer the cli. For complex file tasks I use mc, which is a nice hybrid solution between a gui and a bare cli.
