MM is just better than OOT in basically every aspect.
It honestly boggles my mind how people can prefer OOT. Yes, it has more dungeons, but only 2 of its dungeons are actually good (Spirit and Forest), then you have crap like the 3 child dungeons and Bottom of the Well, and a bunch of mediocre-decent stuff.
MM only has 4 dungeons, but other than Woodfall (which is still better than half of OOT's dungeons), they range from "great" to "best in the series."
Quality over quantity, really.
Add a bunch of sidequests, good NPCs, great atmosphere, and you have a great game. The save system does admittedly suck, I'll concede that point. I had a power outage while I was playing... FFFFFF
