For me, neither of those would fit the description you wrote. They get "broad HF coverage" thanks to YOU having a very good antenna tuner; otherwise they really don't work. Results with stuff like this are predicated on a good ground radial system which you install, and a good antenna tuner which you use. With a great radial system and a very good tuner, all sorts of things work. But for me, that wouldn't be any kind of "quick set up for an emergency" type system.
In an emergency or at a camp site I'd pick a very good screwdriver antenna system well installed on a vehicle which I could drive there; done properly it will work many bands without the need for radials or a tuner, or much of anything other than a radio and a vehicle.
Since for Field Day you are allowed hours to set up, for that I'd pick dipoles strung between trees or set up as inverted vees supported by a telescoping galvanized steel mast (like a Rohn H40) mounted on a drive-on mast support; I can put up a 5-band parallel dipole inverted vee (like the Alpha-Delta model DX-CC) on a slip up pole supported by a drive-on mast support in less than ten minutes and have a good signal on five bands.
