In terms of pure comfort, how would you compare the H&M Charter Sofa and the Chancellor to the Austin High Back ? I am fairly tall with long legs. I sat in the metro sofa today and found it to be fairly uncomfortable, sat in the city sofa and would rate it maybe a 6.5 because the armrests are just too shallow to lean against.

With the Austin High Back a 10
Donovan = 8
Metro = 4
City = 7
Settlement = 5

I have not been able to physically find the models I am interested in, so your input is greatly appreciated.
