I've read good things about the Progress and would love to compare it to my Futur. From what I understand, the range of adjustment, from mild to wild, is greater.
Futur is the most aggressive adjustable you can buy. Even at the lowest setting it is more aggressive then many non adjustable DE razors.
The Progress is one of the least aggressive adjustable on the market. Taken all the way out it is like the Futur set around 2.
Both compliment each other as they are both so different.
Both are very smooth shavers and a pleasure to use.
Here are a few of my adjustable razors (need to take a newer pic with all of them)
