I've played pink Floyd for hours on end over the years and i agree with you that they were awesome. But when Waters left after Final Cut album Floyd went down hill fast without Roger's influence, IMO. A Momentary Lapse Of Reason I played it plenty but couldn't get into it. Division Bell was ok i suppose but I've hardly listened to it.
I like Waters angst he gave Floyd which is still there in much of his solo stuff. I think Gilmour is a fantastic guitarist and for me his finest moment in Floyd was Wish You Were Here album.
I have most solo albums of Waters and Gilmour and their style is like chalk and cheese. I've played Waters solo albums a lot but I just can't get into gilmour solo stuff. I think its too trippy and wishy washy, I'm not saying its crap though, each to their own.
Roger Waters is a much bigger artist than a lot of people think. He sold out Wembley stadium 2 nights on the trot a few years ago. I attended one gig there and it was absolutely jam-packed. He sells out big gigs all over the world for a reason.
