Well, I find REM to be their best and ADHD very close behind. Hyperactive is one of the best songs below 6 minutes I've ever heard (awesome riffs, the real feeling of moving all the time, great piano opening), Egoist Hedonist is great in the way it's unconventional (+ excellent ending), Hybrid Times is great as a whole, and it has one of the best album endings ever. I like Driven to Destruction and Left Out a bit less (the former is slightly too long for me, and the second half is worse than the first imo, the latter is very good but the instrumental part at the end is unnecessary and ruins the atmosphere), but they're good anyway. I've heard it before that DtD sounds like So-Called Friend and except like 3 seconds near the end, I don't find ANY similarities, sorry.
The guitar sound is very good and clean, and even though I preferred the "rawer" sound on REM, it fits very well with the "modern" mood of the album. In general, the album is excellent and very strong in every way, extremely difficult to beat a masterpiece like REM though.
