personally, I feel with everyone who could not make it, but from what I had to learn is,
specs are specs,
and also when formats are too different from each other, it becomes very cumbersome to compare a hundred mixes in one session, and extra SRC would perhaps be not fair to the results, and is also some extra work to do.
there were mixes that I liked a lot, like RJR sounded great, but it was practically mastered already.
but that's just my opinion, as the official writings are clearly on the wall.
some more opinion, randomly picking a couple of mixes because they were on the last few pages:
John
great balances
more reverb than me

love the full round vocal sound, the vocal processing rewards.
I didn't tune mine because organic personality
bass sounds a bit hard
around 2:06 there is a glitch in the vocals, like some signal drop out for a few millisecs
the effect in the stop at 2:51 is great
voc reverb in the finale sounds generally great but for me still a bit much
thanks for the documentation as it reveals some "cultural" thoughts i.e. why something was done or changed, for the sake of style and taste, and about what to prioritize
SDB_12
great balances, good flow
I like the snare sound
not too dry, not too wet, effects come and go in a nice way
good "wet" vocal effects in the rock part before the finale
ld vocal got a great "pop" sound, very clear
at 0:55 the chorus effect on vocals creates a little bit of that "bee swarm" sound
Edu Cesar
you have a lot of great stuff going on in the instruments, it already begins to overwhelm the vocals a bit.
so for a review, vocals might become a bit fuller, with a tad more low mids, voc strength in the finale is very good
good choice in section-wise changes of vocal effects
I like how bass and drums are one tight section, lots of punch
interesting effects on guitars
good flow, goood energy throughout
the strong signs of compression make it a little bit "vintage" which I guess serves the song well, but I wonder what the band thinks on that
Matik
very good mix, only the "male" vocal is a bit loud
keyboards sound great, some guitars contribute more to the keyboard section than to themselves

but no problem, good outcome
rock guitar in the bridge part before the finale has an interesting signature sound, not so trivial
Mork
great one again, everything clear and balanced, dry and punchy
(as a pure matter of taste, I preferred more midrange in the vocals)
it rocks
