Warspite can bring the firepower. But it cannot bring speed or armor if it brings the
firepower. If you want either of the latter two, use the KGV. Warspite is presently
strongest when using the 15" mkIII N guns.

Warspite since its has an extra slot , but forget about armor .

King is a nice ship also , if you like rushing and speed use it.

King George V is a BB2 so the Warspite will be better in theory
A well played KGV can easily take BB4's although in the PoW, even though it's got less
speed, the extra two barrels means you can take anything up to some BB5's alone, which i
don't think the warspite could so. :)

EBB3 of course
