Never listed to Capital Punishment fully so I'm not gonna vote. However, out of the others... Aquemini has held up the best to me. Production is consistently stellar, verses go from slightly above average to . I can't even tell you how many times I've listened to Dre's verse on Aquemini...
I remember thinking that DMX album was hot as fuck when it came out. Has not aged well at all. Same goes for Blackstarr but not to the same degree - I'll still listen to it every now and then.
My copy of Moment of Truth got displaced during my last major move, so I haven't heard it in some time. Maybe I'll buy it on iTunes.
