Nice logs, and point proven. People are like screeching rats yelling frost is dead and its a drwning ship. This particular meumaxu gentleman is so deep in a rabbit hole of blaming blizzard for everything that he clearly lost a few brain cells while digging that whole.
I and a friend on mine play frost dk in same raid and its fine. We are getting 85-99 procentile on hc fights. So its pretty much alive and rocking.
Muh boi Syync who got slightly better gear with t20 4p

However i would say that unholy has a slight edge over frost now. Since some of the fights truly are impossible to maintain 60 seconds breath so i just swap to belt. And as many mention with a lot of run away form boss mechanic unholy just seems more reliable.
All that said the difference is between is very little if you know how to play.
