I suppose I can consider myself a braille scale, as far as AFVs are concerned... Favourite manufacturers are varied, because it very much depends on the type of models. Modern AFVs, I'll put Revell Germany above all I think, but their Pz III, IV and variants are great too, and so are their KingTigers and other more recent WWII subjects.
ESCI and Italeri have originality to their credit, and a decent amount of details. Back in the '80, those were the best AFVs in small scale.
WWI subjects, there's Emhar. Very good stuff. So is Airfix's old Mark I (probably the only Airfix kit of an AFV to recommend).
Matchbox kit are a bit too simple, but some subkjects are not available anywhere else... The older Heller stuff is a bit like the Matchbox offerings.
Older Fujimi and Hasegawa are OK.
But 1/72 is getting more and more popular and now we also have lots of other manufacturers with braille scale stuff. Trumpeter (very good), Dragon (mixed feelings on those), ACE (lots of flash!), Roden (great),.. plus the older manufacturers such as Heller, Fujimi and Hasegawa producing outstanding models now.
And then there's a myriad of more esoteric stuff available in resin, white metal too... I'd recommend MMS and S&S of England, Fine Scale Factory of Germany, Exokit/Retromodels and AlBy of France, Rhino Models in the US,...
Accessories? More and more available from lots of sources now. Scale link, Scale Model Accessories, SHQ, Retromodels to name but a few great ones!
