Big H was a voyeuristic fantasy. When younger (whiter) grime fans came to grime relatively later in it's years... The period where I'm sure a lot of people who were older would consider it if not dead than proven 'finite', that audience came to it without the comprehension of garage or MC culture but with Rap Brain. Westwood's Pimp My Ride, MTV. American defined notions. Victims of media imperialism. I think once you get past the initial fascination you're able to detect a 'softness' in Grime that it didn't try to be like the Americans that was a constant tug of war within grime. You heard certain MCs mock that in others, like Trim once saying about Flowdan's inability to play soccer "He plays basketball because he thinks he's American.". Granted this is Trim, a man who also thinks Eminem is a greater MC than Dizzee so that sickness can haunt anyone and everyone in all kinds of directions.
In any case, Big H was likewise weak. He watched Road Rap happen where it was clear Grime MCs weren't respected for not being emblematic of Street Life or whatever and he craved that validation. He became the REAL ONE in Grime, with videos mocking Wiley and Skepta as they went commercial claiming they weren't 'real' anymore as he returned to grime tail between legs because he was a hack rapper. That chapter wasn't acknowledged to the younger grime audience because who cared, it wasn't Grime. Yet as Grime was clearly obsessed with proving itself as a commercial force, there was Big H to happily court these voyeurs. "I am the real, I am who you seek. I won't betray you the way Dizzee and Wiley and so many others did." The joke being they were never these fans to betray. So in turn their mutual mailiase fed on each other as H provided monotonous tales of Cocaine, guns. No real creativity even to it compared to other North London types who'd mine similar content like Wretch or Castro. Just a hollow note.
In retrospect thank god for P Money humiliating him repeatedly. P Money's a boring and very safe version of grime based on utility but at his worst he'd never be as shameful as Big H was.
