I have used Brigade Games figures together with Foundry Belgians, Tiger Miniatures, and Battle Honors KAR and South African dismounted cavalry and have to admit they mesh together quite well. The Brigade Games figures are the best, in my opinion, the Battle Honors have detail but not to the extent of Brtigade figures. Foundry Belgians also work well for French Tirailleurs without the packs! Tiger figures I have found seem to big a bit larger than the others I have mentioned but not to the degree of being way out of scale, although Tiger offers German askari artillery and pack animals which the others do not (as far as I can see).
Brigade figures are more "muscular" than the others but that's a postivie thing.
Good luck!
