There's been a couple of threads about this. Gypsy absolutely has to be considered among the best, though it may be possible to pick an agreed-upon best show. I personally think that honor goes to West Side Story, but I understand the case for Gypsy. I'd say among the best have to be West Side Story, Gypsy, My Fair Lady, and Fiddler on the Roof.
Interestingly enough, many people cite Gypsy as a show that is wonderful but not necessarily their favorite.
ETA: oops, this was about why. Gypsy is usually cited as having the best book of any musical--one that would be compelling without the score. To me West Side Story has the most amazing complex score, and was revolutionary--geniusly created, and no score or choreography compare IMO. There's a couple of reasons.
"If there was a Mount Rushmore for Broadway scores, "West Side Story" would be front and center. It snaps, it crackles it pops! It surges with a roar, its energy and sheer life undiminished by the years" - NYPost reviewer Elisabeth Vincentelli
