Obviously Clear["Global`*"] would not clear information that might end up in other contexts, whereas Quit[] will clear everything. I never clear the global context - I just quit the kernel one way or another. Restarting the kernel used to be rather slow, but with the speed of a modern PC, there really doesn't seem much point doing anything else unless you specifically wish to preserve some information that is not in Global`. I tend to quit the kernel quite a lot - e.g. between successive runs of a program - why risk the confusion that can arise when two function definitions end up coexisting!
