Tanners sw 10- Not grabbed, not stylish, and pretty awkward, especially the last 360 where he had to "hula hoop" it around, not to mention clipping the deck on landing.
Dumonts 12 - Not grabbed, not stylish, but at least it was big, smooth, and landed well.  At no point was he fighting to get it finished like Tanner did.
If they were both done equally well, then the edge would obviously go to Tanner, but Dumont's 12 was executed cleaner, and landed better.
