Really not a valid argument anymore-5 years ago yes but not now.
The best roofs have surpassed the E series.
THe Zeiss FL with the abbe konig prisms is brighter and sharper in its sweet spot.
The Swarovision exceeds the view of the E and is probibly just as bright.
The new SLC HD is probibly better (yet to test it).
My Leica trinovid BN 10x50 I used to have was a better 10x to my eyes than the SE.
All binos listed are waterproof and probibly more durable than the SE.
Not to put the SE down- it can't be beat for the price.
