I just received a free set of I/OX from Smith after I sent them back my I/O on which the sensor lenses would not stop fogging (they actually sent me 2 different color sensors prior, as well, and they all fogged)...shitty anti-fog but great warranty.
They added more anti-fog on the I/OX lenses, but I haven't even taken them out of the box yet because I'm also contemplating just buying 2 sets of Von Zipper Skylabs, instead: one set for flat light and one for bright light (btw, I found both Skylabs for $30 less than one set of retail I/OX). Granted, the lens change system is relatively easy on the I/O, but I really don't wanna spend any time changing lenses, mid-day.
The main reasons I'm leaning toward VZ is their face foam opening is larger than Electric or any other brands I looked at in the store, plus, VZ is one of the few brands that actually list the VLT rating of their lenses. Skylabs are big but aren't ridiculously oversized like EG2, Fishbowl, Canopy and, to less extent, the I/OX...the astronaut face mask look just isn't me.
