First, both are much better than those cheap things that there are to buy on the beach:
* Glasses can be adjusted excellently in water
* Glasses fits well to the face and water does not clean
* Snorkel is flexible and comfortable to wear
However, there are on this upper level of snorkel sets differences that mainly identify weaknesses in Cressi:
* The Cressi snorkel has a valve on top, which makes close contact with water. This works well when there are waves. But the down dip nevertheless comes in water. The Cressi-Waterdry mechanism that closes up, is not unconditional reason to buy. Rather, it depends on the form and size of the reservoir at the bottom and because the snorkel of Aqualung is (He does not close up) better. In the Cressi you get with even blow out not to dive all the water and must carefully inhale again and blow a second time.
* The snorkel would calm can tolerate a light color on top. That's in the sea very helpful to be recognized by boats.
* The "Area View", so the solid disc, is also no absolute reason to buy. The Cressi runs noticeably faster. You have to take a lot more precautions to protect the goggles before starting (Just google). In my opinion, it is up to the large, less well-insulated disk space that is faster cold. In Aqualung without Area-View, I did not feel restricted me in the field.
The good thing about Cressi snorkel, the removable clip. That has not the Aqualung.
