I would take them over my speedo speed sockets for comfort, and over my head venoms for visibility. But it's a tight call between all three.
Pros: Clear and very adjustable. Decent field of view.
Cons: The dangly elasticated nose piece is fine when swimming but is annoying and ticklish resting between sets. And replacing that with the string and tube makes them uncomfortable over the bridge of the nose. So for me, it was back to the elastic and in the bottom of the bag as spares or for long swims without rests.
Overall it's still the Head Venoms for me on most days though, despite their field of view problems
