Empiricism or Quintessence?

if i were to choose between those two, id go for quintessence. but but if i were to choose between all albums, id go for the first two.. those are my faves
 
I choose Empiricism because , it sounds more into the progressive-technical direction
 
Empiricism has more varied and interesting song structure than Quintessence. Then again, there are no songs like The Presence is Ominous and Colossus. It's a tough call, but IC Vortex (my favourite vocalist in any genre) wins me over to Quintessence, although I listen to Empiricism as an album much more often than Quintessence.
