By far the FV430 range is the best vehicle. It has forefilled just about every roll with-in the British Army and is still going. It has been everthing from a missile launcher (Swingfire), Artillery gun (Abbot) Coms, Medivac, APC, recovery, Mine layer, Mortar. It is well protected, non of this lightweight Ally stuff.
The next generation is just as awsome, the Bulldog is a much up-graded vehicle. From the outside it looks almost the same but dig a bit deeper and the up-grade unfolds before your eyes. Bulldog can carry all types of weapon. Mortar, 7.62 GPMG, 50cal either single or double and of late the new RWS. So for me, I think the FV432 is the best.
