I think M-x grep and M-x occur should have as similar a UI as possible.

I'm not sure I agree: grep is for searching many files (external to
Emacs) and occur is for searching a single buffer (internal to Emacs).

I've always found it baffling that if you are in a *grep* buffer you get
a Compile menu with entries like "Next Error" to go to the next match.
I've always found it annoying that C-x ` works for *grep* but not for
*Occur*.  (I guess M-x grep is closer to M-x compile for historical
implementation reasons.)

Not that C-x ` works in all buffers, not just the *grep* buffer.  Making
*Occur* buffers just like *grep* and *compilation* buffers would be a
lot of work, but if you just want C-x ` to "do the right thing" in
*Occur* buffers, try this patch:
