I have Dunlop Winter Sport M3 on the sedan with 205/50R17 and Bridgestone LM-22's on my cab with 225/45R17.
They are about the same noise wise. We haven't had any real snow yet, so I can't comment on the snow performance between the 2. In the dry, the Bridgestones stick slightly better on the corners (but this can be attributed to wider tires).
The LM-22 is replaced with the LM-25. The tread pattern is slightly different, but it is pretty much the same tire (in the sense that the same compound is used throughout the tire, instead of the top 50%).
They are both good tires and you can't go wrong with either. The Dunlop Winter Sport M3 was cheaper brand new if cost is consideration.
