So that is a great question. I don't have any direct experience with the 441, but I know others who have a lot of time in them.
I have heard nothing but good things about the speed, efficiency, and flying qualities of the 441. Everyone I know absolutely loves them. And historically, not sure about now, the 441 has cost more to purchase.
That said, the 695B (in particular) is pretty darned good. I'm not sure how they compare on useful load, but the 695B is pretty hard to beat. It might be a few knots slower, but it's very competitive with the 441. I have also heard that the 441 is lighter, and arguably not built as well, but I can't really say for sure.
I think the big issue, in addition to the purchase price, is parts availability and support. Cessna would prefer that all the 441s are retired and replaced by Citation M2s, while Commander is still, at least for now, in the business of selling parts and supporting the airframes.
