First 2 in particular, and also MAYH. I prefer the whole melodic-twin-independant-guitar thing of the first 2, and MAYH was my first so that holds a special place for me. Deliverance is quite cool, I dislike BWP, and SL, while it is a perfectly good album, doesn't do alot for me (atleast not to the extent of the first 3, I don't hate it or anything, I just can never get motivated to listen to it, I go to pick it up and think "nah, I'll listen to Orchid instead.....")
