"Surprised that BA is doing best job from what I can see! Please compete w them on these factors"
The reason people like me like the TT version of doing tents is because we like the way they are made as you like the way the BA is made.
(of course others like the MSR and so on...)
It has to do with personal likes and dislikes, see And D comment for a start.
For solo use , for example, the Moment (fly/inner/stakes/pole) is about the same weight as the FC2UL ,(the Platinum has a much thinner fly) big enough for a large adult and with good vestibule space.
sets up in a minute (yes faster than the BA...) with two stakes only, Add another 2 and is ready for some weather.
Sets up dry, unlike the BA, so inner and fly together.
Now a nice feature of the Moment is the two doors with the inner (tent over there...) that can be shifted towards either entry point so that if the wind changes you can use the other side.
But of course if you ike the BA that is what you should get...
(BTW, I was using TTs for 5 years before I became part of the brand, and yes I do know what the BA shelters look like in the flesh...)
