I've seen brief discussions regarding this but nothing real in depth.
Not that I am the voice of reason at all, but here is my take on the pros and cons.
Weight (due to stretchers), probably more unstable, more complicated and costly to build. That would be the negative side.
On the positive side; more comfortable to sleep in (IMHO), easier to DIY upgrades (weather shield, bug netting, under quilts) mainly because you have a flatter surface to work from.
