I camped at Loch Lomond last year, right below the lake (where it can be super windy). My softshell tent held up just fine, and the noise wasn't all that bad, but I also made sure the rainfly and any flaps were pretty well secured before I went down for the night. I woke up a couple of times due to the wind, but my son (4yo) slept like the dead.
The only reason I'd go hardshell would be the takedown time. On my own, It takes me about 2 minutes to set up my softshell, but about 10 minutes to take it down (maybe 5-6 min if I have another set of hands). As much as I hate the damn thing, the Rhino Rack Pioneer platform makes it much easier, since I can basically walk around the tent to take it down without worrying about damaging the roof of the truck. It took forever to tear down the RTT when it was mounted on the stock rails on my last 100.
I just haven't been able to justify spending $2,000+ on a new tent to save 7-8 minutes of time...yet...
