I'm curious as to what everyone is basing their vote on. I've breathed a lot of regs, and for the most part can't tell any significant difference in the breathability. What I notice more is the "feel" of the second stage.
I was always perfectly satisfied with my old USD Glacia/SEA. It was durable, easy to rebuild, and breathed well. Some of the newer regs have nice light weight seconds which are more comfortable, but they don't breathe any better.
I can understand the desire to have lighter weight equipment for travel, but as for durability I've never seen any reg failure that wasn't maintenance related (and very few of those!). I've seen regs as green as springtime in Ireland function just fine. This says a lot about the inherent durability of most reg design. So beyond that, what's the big deal?
