That is better than most but my problem is the dance one has to do to get around the geriatric who stands the whole flight with his/her junk pressed into your shoulder or face for 2/3 of the flight because there is no where to go. At least with twin aisle you can do loops or go a different route to get to your seat etc.
I'm not saying it wont work I'm saying 4000 miles that way is not for me.
