You pay your money, you take your choice. All are probably as appropriate as each other, each have their fans and their enemies.
It also depends a bit on where your apiary is- if you plan to move bees about a bit, the smaller hives- National, Smith etc are much lighter, and WBC is best avoided. If you plan to leave them in one spot, then it is less of an issue.
i suspect that will be BS nationals either with brood colony in a super and standard brood or brood colony in a deeper 14x12 brood box
most beehives sold are bottom bee space nationals and on here Hivemaker and Tom Bick and many other make them...much better than some shop sold ones
Or ask rooftops for his Poly langstroths...more difficult to source nuc of bees for but they are Top Bee space, cheep and bloody good quality, however few in my BKA use langstroths, perhaps wait for rooftops new Poly National he is intendeing to sell later in the year.
Smiths,( TBS hive mainly scotland) Commercial ( BBS hive mainly east anglia) dartington/Beehuas (14x12 sideways hive) all have their devottes but are there any in your area
And for the hedgecoe hive demonstrated at thornes stand at Stoneleigh..did any one see it
