I'm not sure that having two more hours a day will free up your weekend, I'm kind of leaning to 4 days a week because you can actually have useful time.
Personally, I wouldn't object to 3 days of non-stop working till the midnight to have 4 free days a week. Things won't pile up and instead of having just evenings, I will be able to leverage full days which will give me better freedom of movement away from where I live.
The 5 days a week schedule is my primary reason that I'm not in a full time job since a while. I was at home at 18:20 max, yet I never had time to do anything for myself.
