Brendan,
I've seen a few of Levy Rozman's videos, and he's good. He's achieved a remarkably large following, and deserves credit.
Latvian GM Arturs Neikšāns is a chess streamer I really enjoy. His banter blitz sessions on chess24 (perhaps archived on youtube?) were great, and I like his tournament commentary. He's pretty obscure, much less known than Levy. Also an articulate gent, most impressive for a non-native English speaker.
GM Peter Leko (I saw him signing autographs
Lékó Péter as a teenage prodigy at the Intel NY Rapids in 1995, though he seems not to have played in the event) is my favorite chess commentator. Tremendous erudition and infectious love of the game.
