The sweary thing is one way to distinguish from the competition I suppose, but all my favourite comedians manage to amuse without regular obscenity, in part because they reserve it for when emphasis is needed. (I'm not prudish about swearing - I swear like a trooper at home - but I do seek more thoughtful / less cheap material from my comedians.)
I also note that he's adopted - though not as savagely as many - that favourite youtube technique of removing the full stops from the end of every sentence, leaving the whole monologue sounding like one long breathless sentence replete with visually jarring cuts. It's a horrendous editing technique. Evidently enough people can put up with it for it to remain popular, but I just quit any videos done in that style.
