Hard to say - all depends on the magnitude of the threat from Germany.
Going full KGF with a pretty standard German opening round means that the sea zone next to Algeria is threatened by 2 subs 3-5 figs and a bomber.
I almost always buy an AC + Destroyer.
Maybe also a Fighter (UK maybe require 1-2 figs on their AC).
this leaves room for 1 transport + 1 tank
I often land in Algeria with 4 units round 1 - meaning I sacrifice the two transports.
Giving me the possibility to move in next with AC + 2 figs + cruiser +2 dd and maybe join up with the UK navy.
Germany can beat this, but not likely without substantial losses, if they do my next buy will be similar, and reach Europe together with the pacific battleship.
