My trips are predominately in the Sierras and in many cases above tree line. I switched from a Tarptent to a Free standing tent. Part of the reason was that (IMO) non-freestanding tents tend to need a larger area to stake out (not all, but mine did). Combined with choosing a flat spot and being out of the wind, it tends to limit the places that you can pitch a tent. Coupled with the rocky substrates of the Sierra, I found that it has been much easier to set up (and move/optimize) tent locations. My 2 cents.
Great information. Really focused on what I'm thinking also. I went the other way: From a free-standing (Brooks Range Foray) to a Tarptent Strato Li. Yes, that tarptent is definitely a bigger footprint - which is another concern. The Brooks Range is a strong tent but really small. I like all that space inside the tarptent - but I have the same concerns you mentioned. That Strato Li might not be the best option for that area.
That is often a factor especially in a group.
Another factor not mentioned is simplicity and reliability. Non-freestanding tents tend to be simpler with fewer parts to lose or break. I've been in groups where both have happened. And I witnessed an eye injury caused by a bent hoop pole springing back out of control.
