Now that I've given the time to listen to both of these in full and digest them a bit I'm going with Vektor hands down. I feel like Outer Isolation is Vektor firing on all cylinders while Revocation has an album even better than Chaos of Forms in them that we've yet to see.
8/25 - BAT / ChainBreaker ?
8/30 - Morbid Saint / Vektor
9/13 - Sete Star Sept ?
10/3 - Prosanctus Inferi / Horrendous
