Rafter and Moya were obviously big forces as they reached No1 that year but injuries meant they slipped from the top ranks.
I don't believe however, that Andre's hot streak comes anything close to Federer's 2004 or 2005 in terms of dominance. Andre won a mere 5 titles in 1999 and finished the year 64-14 I believe, and the Australian Open was his only title in 2000 I believe.
In terms of overall dominance, you are correct, Andre's streak does not compare with Federer's. Few players in the Open Era do... except perhaps McEnroe in 1984.
However, Andre's 4 consective GS finals on different surfaces was a remarkable performance at the slams, one which hasn't been equalled by anyone else.
