In number of recovered artifacts (30,000+) and the size of the ship the Vasa is definitely the bigger find.

However, the Vasa was in much better condition and the recovery process went much smoother, so the recovery of the Vasa required "only" some 1500 dives (although some of them, like laying the supporting cables through the mud under the ship, were very dangerous and required skilled divers) as opposed to the 25,000+ dives required to recover the Mary Rose artifacts.
