My personal verdict: Barrett Period(PATGOD to SFOS): Very Good and different from anything else they did; But IMO you cannot compare it to their later greatness. Waters Period (SFOS to the Wall*):The best music ever created, the music that they are famous for, the music so many of us love, made possible by the synergy between Gilmour, Waters, Wright, and Mason. Classics; every one of them! Gilmour Period (MLoR and TDB): After Roger quit in 1985, the band sort of fell apart: These last 2 albums pale in comparison with the masterpieces they made with Waters, and, as such- not to mention that A Momentary Lapse of Reason was as much a David Gilmour solo album as The Final cut was a Roger Waters album- are, IMO, mediocre overall, the one exception being the gem that we know as High Hopes. * I have omitted the Final Cut because, aside from a few guitar solos from David Gilmour- and vocals on "Not Now John"- it is, essentially, a Roger Waters solo album.
