I think in terms of different units we still beat most of those. For example; Khorne has a freaking paintbundle listed on the site, they still have a boxed game against slaanesh, 2 underworld warbands and khorne has 2 start collecting boxes. That's already 6 items that are basicly doubles of other boxes, or don't really matter in AoS. And then there's also the fact that khorne has multiple slaughterpriests and exalted deathbringers still hanging around while we only have 1 variant for every model.
Maggotkin has 3 different SC boxes a tree set & a single tree.
Slaves to darkness still has a battleforce and army box and of course the entirety of warcry.
Half of the new skullpeople boxes are bundles.
Half the oger range consists of various man-eaters which are sold seperatly for some reason.
We're still one of the larger armies when it comes to sheer unit count. Only skaven, CoS, LoN & SCE seem to be genuinly larger in that aspect.
