The GB SFA is very nicely made, but I'm not convinced it's the best choice for typical British use.
If you're traveling in boreal forest on foot, and need to fell small trees for shelter and long log fires, it's great - not too heavy and the narrow bit takes out big chips. I can see why RM chooses it for this kind of thing. Quite good for carving too.
But often in the UK it will be mainly used for splitting wood for the fire, not felling, and for this a broader bit splits better. I used a SFA and a similar sized Wetterling (Swedish, similar quality, but not as pretty as GB) at a meet and everybody felt the Wetterling split better.
I've never taken an axe when traveling any distance on foot in the UK, because I don't like the weight or the attention. Splitting wood for small campfires can be done with the knife. At home, or at a meet, with a bigger fire I think a bigger, broader axe is preferable - with a 24" handle as suggested by BR. At home I find the SFA is just not enough AXE for some logs.
The Cold Steel tomahawk is a nice piece of kit but inferior to the SFA for either felling or splitting. Good bit lighter though, and very easy to replace the handle when necessary.
