The reason being is that these chairs tend to have better back and butt support for longer periods. This particular model allows you to recline as well, which can be good. It'd mess up your neck if you're doing it every day for weeks on end, but the occasional park day would be fine.
I can second both the recommendation and the style of the ones to avoid. I spent several weeks camping and working remotely using the first one over the winter (here in Florida that’s the best time to camp). Tried using the other style too, but always found it uncomfortable for head down work.
