Ok, let's keep it at least within core rules.
I also wasn't considering prestige classes, but if you want to rule in the DMG ones, do so but factor also the prerequisites... I mean, let's not say the light-weapon fighting style wins because you can be a duelist after spending 3 feats (2 of which unnecessary for the style) and at level 11 or more you get precise strike... which IIRC it's the ONLY duelist feature which works only when using a single-handed weapon.
