i get roughly the same flavour on a plume veil but way less vapour.
but the real benefit, like i mentioned earlier, is that i dont have to worry about it leaking even if its on its side.
the build is very different but its really easy after a couple of builds and you're used to it.
i go for a single horizontal though as i find it gives better flavour than the dual vertical its built for.
think most people feel this way as well.
