I like watching anything. When people rotate smooth and slow, it generally means they're more comfortable with what they're doing. That says a lot about ability.
As far as larger spins are concerned, and comps, I think people should remember what difficulty is all about. Cork/misty/rodeo 5s are great tricks, but to me, comps are about ability. If someone throws a shitty looking 9 or 10, should they automatically beat a 5 or 7? Of course not. But if you can spin a 9 or higher and make it look good, then you're doing something harder. Every day of the year, you can ski how you want, and do whatever tricks you like doing. But if you're entering a competition, you're trying to show you can that you have more ability than the other skiers in the comp, so you should do the most difficult tricks you can that still look together.
Look at it this way. If everyone in a comp throws a cork 5, who wins? You may say the person that does the one with the most style. But isn't everyone's style different? That's the whole point of 'freestyle' skiing. So in a freestyle comp, it should really be who can do the most progressive, difficult tricks that dont look like shit.
