i've been out of the ytpmv loop for so long that:
A) i don't even know the full extent of who's on that scene nowadays
B) plenty of the folks i Do remember from Way Back When got copyright-striked to oblivion and are using a new channel/handle i'm not really familiar with enough to remember
C) all of my favorite YTPMVrs would be based on the videos they made back in like, 2010, and i know that ain't representative in the slightest of the increased quality & skill expressed by folks today.

i know that this is kind of a non-answer but the list is both too big to count in fear of missing folks/friends from the tally, and also too fuzzy in memory to detail properly.
i'm the wrong person to ask abt this, honestly!
