Right. There are really (at least) three types of completion.
1) bash completion using bash only
2) bash-completion using the bash-completion 3rd party addon to bash
3) emacs shell-mode completion
All three of those do completion. The second extends onto the first.
They all have slightly different behavior with pluses and minues to
each of them. Personally I only use 1 and 3 and don't miss not having
2 but I can understand people wanting it inside emacs.

bash (1) does this:
Attempt to perform completion on the text before point. Bash
attempts completion treating the text as a variable (if the text
begins with $), username (if the text begins with ~), hostname
(if the text begins with @), or command (including aliases and
functions) in turn. If none of these produces a match, filename
completion is attempted.
touch foo bar
ls f<TAB> will complete foo
bash-completion (2) has many additional completions including
completing options for commands that support --help.
ls --so<TAB> will complete to --sort

That was specifically why I mentioned that C-x is mapped to C-c! :-)
Because if that isn't known then you are trapped. But knowing that
allows you to switch buffers away or other commands.

Or kill the buffer with C-c k RET which I usually do when done in
order to clean up and free up memory.
Also as Oleksandr Gavenko wrote the following keys are very useful:
C-c C-j switch to term-line-mode (effectively similar to shell mode)
C-c C-k switch to term-char-mode
When in term mode I switch back and forth between those modes *a lot*
as needed to deal with the immediate task. Some things are easier one
way. Some the other way. Relevant to this discussion with C-c C-k
you get bash completion. With C-c C-j you get emacs completion.
