For me, after the Black Album
To me, even if Mustaine and Friedman are techinally better players than Dimebag, most of their solos never really made any impression on me. Personally it feels like the solos were just there cause the song needed a solo (with a few exceptions). With Dimebag, the solos gets stuck in my head and I find myself several times reversing back in the song to hear the solo again. Most of Kirk solos are all very well composed and well played in my opinion, I don't see what all the fuzz is about.
