I used BITOG as a good mark for starting the research, then the reviews from tirerack, treadepot, tire-easy and many mentioned on various threads.
Then went with the reasonable choice, but not the cheapest.
Also used local chains before BITOG, but I was less informed and with less money in my pocket....
The only consistent firm was Cooper (3 sets on 3 different vehicles)
But I would say I'm not brand loyal.
