I'm not sufficiently familiar with the TA songs listed, so this will be all about the others.
Group 1: Disappear is, at best, meh, and Raise the couple of times I've listened to RTK on Score I haven't been impressed.
Group 2: Possibly my favorite DT song of all time and my least favorite paired up.
Group 3: Blind Faith is a top 10 DT song. TOT is good but not great.
Group 4: Misunderstood is great. LITS is very much not.
Group 5: Glass Prison is very good. Peruvian Skies not so much.
I think I have to go with group 2 solely on the strength of ACOS
