Always loved watching Rafael Lovato Jr's matches as he always goes for the finish rather than try to hang out and stall for points.
He plays a very straightforward pressure game, sticking with pressure passing and then crushing top control, usually ending the match with a collar choke or kimura. I prefer this to the crazy spinning inverted berimbolo type games that are prevalent in the BJJ world these days.
Check out Lovato's video below which shows his finishing and submission prowess.
