As a wise man once said "They hated on Jesus too..."
The 410 camp in particular are picking drums that are incredibly irregular, that one "Diligent" tune someone posted here not too long ago and compared to jungle vibes was not surprisingly far off? As MCs they don't do much with that but it shows just how much more rhythmically complex the Road Rappers of this generation are. A bunch of them are the kids of grime in fact, so it makes sense that compared to the stiffness of Giggs they're demonstrating a comparative looseness.

Mazzamurda, who did a bunch of 410 stuff did this 86 (a crew loosely affiliated with 67) tune, and its crazy how the 86 kids have a sense of rhyming alongside not the drum pattern but to the drum embellishments that Mazza loves to try. Whereas just a year before that, most of the rappers are rapping to the 'grooves' of the orchestral sample bits.

And if you don't believe the connection to grime for this generation of road rap's there... Lemme tell you
OH IT'S THERE.
