Diff oils etc.

What do people generally use for diff and transmission oils, whether or not you use 75/80 or 80/90, I've always been lead to believe that GL5 should be used for diffs and GL4 for gearbox and tranny box, but the other day I had my first glance at the Haynes book of pork pies at a mates house and it stated GL5 across the board, so what's peeps preffered choices.
