the old master i think is the best sounding, because it sounds the best as a whole, even though the kick drum is way too much and the guitars are a little quiet.
the drums arent as overpowering in the others, and the guitar sounds better in master 1, but unless you were doing an entire remix of it I would suggest the old one sounds the best.
Honestly, the music sounds great, and is very well written. But I would add some more rhythm tracks to the guitar sound.
Like, layer an hm2 or metalzone or Valvestate style tone to make it a bit wilder and give it some more personality- blend that with the tone you've got going on
all in all, very cool, reminds me of a more concise version of autumn leaves circa "as night conquers day" but with a more nodtveit vocal delivery.
