For me, it's Max and Liz completely. They weren't always making out in closets like Michael and Maria were, but during their hot moments, it was...HOT!!!

There was also so much opennes between Max and Liz that made their passionate moments so much more intense for me. Michael and Maria didn't really have--at least Michael didn't really--until the end of season 2 and season 3. Also, I wasn't really attracted to Michael until season 3 when he finally grew up and started being person I thought was good enough for Maria. with Alex and Isabel, they weren't really hot, but they were cute--at least when Isabel wasn't messing with Alex's head and heart.
