OK we disregard all the particular brands you pointed out in the first post (as it would, by your standards, be weird and pointless to regard what you point out there, by your own standards, so weird and pointlessly) and look at the practicality of the one-man, no-fly, cheepy, nylon tent and the practicality of the fly, more expensive, ultra-light, 2-3 man nylon tent.
My conclusion: If I am going to pack a tent I prefer to get one that is worth packing and not a cheepy, one-man, no-fly tent that might be better if I cut it down the middle and used it for a tarp tent that has some bug netting attached to it.
