Thank you Christian.
Not quite what I was looking for.
But this is:

function! CurLin()
if v:version >= 700 | setlocal cursorline
else | normal! zz
endif
endfun

function! PrevDQ() " Prev Diff or Quickfix
if &diff
normal! [c
else
try | cN
catch | clast
endtry | call CurLin()
endif
endfun
nmap <silent> <F7> :call PrevDQ()<cr>

function! NextDQ() " Next Diff or Quickfix
if &diff
normal! ]c
else
try | cn
catch | cfirst
endtry | call CurLin()
endif
endfun
nmap <silent> <F8> :call NextDQ()<cr>
