its insulting to compare RH to PF.
For one thing, PF comes from an era where good bands were plenty.
Pink floyd was methodical, original and always progressing its sound. Each sound they made was as if it was made for a reason. Images come to mind. They were somehow able to mix visual images with music.
here are some lesser known tracks progressing chronologically (more or less):

Echoes: some causal PF listeners might not know about this. Unfortunately I could only find it synced w/ the ending of 2001: A space odyssey. So if you don't want the ending of the movie spoiled, dont watch this video:

And here is the final song, of the final album of the pre Dark Side of the Moon era, as if they are departing from their native home and getting ready to become recognized:

If you had to pick an album, that was the greatest album of all time, DSOTM could easily win that. Though I think w/ MJ's recent passing, most would rate Thriller over DSOTM (fair, imo, both are amazing).

After DSOTM, it is all down hill (imo), yet they still produced excellent two excellent albums: Wish You Were Here and the Wall. Animals, I would consider just shy of excellent.
Some post DSOTM highlights:
SOYCD I and II

amazing how different their music is. I mean SOYCD was totally diff, compared to DSOTM and Obscured by Clouds, but by the time animals comes around, it is totally diff. Possibly b/c Roger Waters was taking things in his direction.

An analogy I would make is, PF is to RH like a HSNL soul crusher is to a NL400 grinder.
The NL400 grinder will put ~99.5 % of poker players to shame.
The HSNL player is by whom standards are set.
