I tend to use git.el - which provides the M-x git-status command - and therefore
ediff. It's not necessarily the best git interface, but I've been too lazy
learn anything else so far. git-status allows you to do basic git
adding/committing etc. and will show modification diffs.
Given a git-status buffer, a conflicted merge will show up with certain files in
red. You can then view the conflicted versions side-by-side positioning the
cursor over the conflicted file, and using the key-sequence 'd E' to start
interactive merges in ediff mode. Afterwards you have to save the buffers and
mark the file as 'resolved' in git-status ('r').
There are other things you can do in a git-status buffer. M-x describe-mode (C-h
m) and M-x describe-bindings (C-h b) will provide some idea.

git-status works with all the above. I don't use git-mergetool at all.
To keep things in one emacs session I sometimes use git directly in emacs shell
buffers. i.e.
- Run emacs
- Open the repo in dired: M-x find-file <path to your git repo>
- Invoke git-status: M-x git-status
- (do stuff)
- Open a shell M-x shell, M-x eshell, or M-x ansi-term
- (do more stuff)

As I said, I don't use git-mergetool, but git-status should allow most basic
things in fairly straightforward way. For anything more complicated (e.g. git
commit --amend, or git add --interactive) I open an shell in emacs.
If you tell git to use emacsclient as the editor, and then git commit and co.
will open an emacs buffer so you can invoke git from the command line without
leaving your emacs session. To do this:
- invoke: git config --global core.editor emacsclient
- in emacs: M-x server-start
(or add "(server-start)" to your ~/.emacs file)
At some point I might check out magit. I'd be interested to hear about
comparisons between git.el and the alternatives.
Cheers,
