I don't think I've posted in this thread before even though I voted (Gilmour) so I'll add my two cents. I came into Floyd kinda backwards. Aside from the ubiquitous "Another Brick In The Wall Pt. 2" I don't think I'd really heard any Floyd until Jr. High when I got a copy of "Momentary Lapse of Reason". I loved that album but didn't have the resources we do now adays so didn't really expand my Floyd horizons till much later. My exposure leaned very heavily post Waters until a good bit after that when I got Dark Side and The Wall. I'm only now really exploring some of the other early stuff. Due to that I am a HUGE fan of Gilmour's guitar work and also enjoy listening to him on Vocal. I like Waters just fine but I don't have the same love for him that I do Gilmour.
Just as an interesting data point, my PF full album exposure probably went in this order:
MLOR, Wall, DSOT, Divison Bell, DSOTM, Pulse, WYWH, Meddle, Saucerful, Animals, Endless Rivers, More Relics
I have yet to hear PATGOD, Ummagumma, AHM, Obscured by Clouds or Final Cut
