This was tough for me because I love both albums but prefer AC/DC(Bon Scott era) way above Priest. I went with Priest for a couple reasons: I love the remastered version of Unleashed in the East because it included my favorite Priest song "Hell Bent for Leather" along with "Delivering the Goods", "Rock Forever", & "Starbreaker" which just added so much to the already phenomenal album. "Exciter", "Green Manalishi", & "Diamonds & Rust" are really superior to the studio cuts (in my opinion). On AC/DC I love the live version of "The Jack" which alone almost gave AC/DC the win for me but the album is missing "Sin City" which was a very important song in their Live sets with Bon as was "Live Wire" which they opened with all 3 times I seen them with Bon. "Whole Lotta Rosie" is great with the Angus chants but I feel the live version falls a bit short of the studio version. "Rocker" was also an important part of their set & the 3 times I seen them live in the 70's they jammed it for a good 7 or 8 minutes. This version is very good but it's over before it starts (Much like the studio version). The live versions of "High Voltage" & "Let There be Rock" really captured the spirit of a Live AC/DC show back then which was another plus for AC/DC but I had to give the win to Priest
about this one, before I decide.
