The point about there being less to complain about in NXT is more in reference to what I feel is more consistant booking. The booking is belieable without being overly silly like AEW and RAW/Smackdown can be... paired with an in-ring product that is as good or better than anything else on US TV, and yes I'd argue it's a better alternative to main roster WWE. Vinces main product is all about sports entertainment... thus a product with less emphasis on that makes for the strongest alternative because it's more different.
