Can't comment on the Vaikobi. But really grew to love the Mocke last season. The material used to fashion it seems to dry almost instantaneously, and I never got that funky, mildew, smell on it the next morn if I did a knucklehead move and forgot to take it out of the truck the day before...
The Mocke also seems to breathe very well on the really hot days. I have other lightweight vests that feel like they hold in the heat more than the Mocke in those higher temps.
No remount issues at all for me with the Mocke. I basically exude the grace of a clumsy Galapagos tortoise, climbing atop it's mate for some bow..chicka..bow..wow!!! when I am remounting my ski, so in my case, if there could be a problem, there probably would be a problem.
I also like the color of the Mocke from a fashion perspective. It matches the orange of my cheap artificial tanning product, as well as the crimsony tangerine hue of my oft sunburned and bloodshot, pale Nordic eyes...
