I prefer Skullcrusher... mostly for his design. He seems to be a better overall anatomical match for Stoick. Whether or not he is a particularly developed dragon is a small downside. Thornado does have much more backstory that we have seen. However, I was never really convinced that a flat, tidal class dragon was a good mount for Stoick. Plus... as far as things go, I generally think the movies are a lot better than the series, and we see Skullcrusher in the movies and Thornado in the series. Still, they are both good dragons, and they are both fortunate to have bonded with Stoick.
