Contrasted with Vince McMahon's affinity for Caucasian and Samoan males being placed at the top of the male booking hierarchy and blonde, model-centric females at the top for the women, NXT has a much broader and more diverse roster which appear to be given equal chance at success.
The NXT roster also boasts an incredibly rich international roster from at least 5 continents that are hardly ever stereotyped in a storyline or held back for not speaking the language or having a different accent.
In addition, NXT boasts a tremendous array of wrestling styles and personalities. Whilst some old-school fans abhor the "vanilla midgets" and high flying style common today, NXT's current roster has both cruiserweights (Johnny Gargano, Adam Cole, Ricochet) and super heavyweights (Lars Sullivan, Keith Lee, Otis Dosovic) in near equal proportion. Traditional brawlers (Pete Dunne, Oney Lorkin, Danny Burch) and martial artists (Aleister Black, Kyle O'Reilly, Shayna Baszler) are as commonplace as flippy guys (Raul Mendoza, Fabian Aichner, Mark Andrews), while women wrestlers range from big indy names (Candice LeRae, Deonna Purrazzo) to international stars (Io Shirai, Kairi Sane) to Performance Center-trained upstarts with massive potential (Bianca Belair, Lacey Evans). There's someone for everyone.
