They do cost more than other styles (understandable, since there is more to them). But some of us had to find out the hard way that it's far less expensive to buy one pair of chains than to end up buying 3 pairs. I guess the upside is that after having used all three styles on the same tractor, I ended up with a good idea of the differences between the three.
I'm not saying that Euro-style chains are the only chains for everyone. However, for my use (plowing an icy driveway with a steep hill, using in our hilly woods on side-hills and rough terrain, and driving over the road for several miles or on hard ground on a regular basis) there is absolutely no comparison. Yes, I did that with my ladder chains, and with my Duo-Grip chains, it's just a whole lot easier with the Euro-style chains. I don't have to choose between driving at half speed or shaking myself and the tractor to pieces when on roads or hard ground, I don't find the rear end sliding sideways and leaving me stuck against a tree when operating on sidehills in the woods, and I don't have the tractor get pushed sideways when following a winding woods trail while towing a heavy load downhill. The loop in our driveway near the house was freshly paved last summer. I mostly stayed off of it with the tractor if the chains were on in the heat of the summer. This winter, I've been on it after each snow. Because of the continuous good traction, I have not left any marks from these chains, despite the studs.
I gave my brother my 4-link V-bar ladder chains, and he is quite happy with them. They are well suited for his needs, and easy to get on and off once you know the technique. He clears his own driveway and a couple of neighbors with his loader. He does occasionally take his tractor into the woods, but his ground is much more level.
The V-bar Duo-Grip chains have been sitting in my garage for several years now, waiting for me to get around to selling them. They were only used 5 or 6 times. The forward and lateral traction was very good, but the first time I made my 5 mile run to another property, I knew I could not keep them. For someone without the need to operate at higher speeds on hard ground, they might be perfectly fine.
I have never tried double ring chains on this tractor. The farmers around here tell me they are the best in mud or in the clay soils found in some areas around here. Since I generally avoid working in my woods in those conditions, I've never felt the need to try them.
