I'm probably not the best one to answer this, considering my noobness, but I don't seem to have a preference. I like both my MVP2 (box) and Provari (traditional). They are both very different in form, but still do the same thing as far as 'general' function. I prefer to use my Provari, now that I have it, but I don't think that has anything to do with it's form in this context. As with anything, it just comes down to personal preference (and yes, I realize that isn't at all helpful).
