I guess, it depends - white hat got more easy, white hat methods do actually work in the high competentive niches.
Blackhat became a bit more difficult, a bit more technical - but is basicly really much faster, to earn some k in a month^^
But this involves more then just installing Wordpress and spaming links (wich still works and the November Spam update even made it better^^), but you might need to go on big scale, handling some k Domains and managing all of this means some technical knowledge and coding as well. You might need to cloak the shit out of the clicks, you want to be anonymous, in most cases, cause of legal stuff, all of that made black hat harder - or perhaps just more professional.
