Ultra shielding is a very thick layer of dense rubber, much like what the SMP has. A bit over kill, but the best way to avoid flats as tires go (I like tire liners a lot.)

Vittoria Hypers are very similar to Marathon Supremes, but have a higher thread count.
Vittoria Randos are a less crazy version of Marathon Plus, somewhere between a HS368 and SMP, but are much more comfortable, and roll better than the HS368's in my experience. I'm guessing they're way more lively than SMP's, but I've not ridden those since they're so over priced.

You're right!
Would have never guessed that triple shielding is less than double, leave it to the marketing department...
