I first used Win95m MS DOS and QuickMenu. QuickMenu was so nice and easy to use. Then Win95 came along, and it took some getting used to, but I liked it after that.
Then 98 came along, and it took a little getting used to, but it was good after that. Nice and small and stable, too, IIRC.
Then the move to XP came, and that took some getting used to, but in the end, it worked. Especially seeing as you can tell the menus and everything to act in the "classic" way of 98 rather than the new XP way.
