Those offered for sale are called ladder chains - very nice ladder chains in fact. With ladder chains, tires will make contact with the road intermittently - hence the noise and the bumpy ride. A tried and true design, and the most common.
Ladder chains are generally not recommended for vehicles with ABS or traction control systems; I think that diamond or zig-zag is a better choice for those. Based only on what I've read about the drivetrain, I'd assume that you can set the transmission to 4WD (not AWD) and the L400 & Pajero's would be fine.
There are also diamond, cable, and link styles; and custom patterns too. Diamond are what I am most familiar with. See below for some idea of the variety.

Zig-zag chains maintain contact with the road throughout the tire's revolution, and are generally said to be best overall. Here's a photo of zig-zag.

There is also the matter of regulation. I'm not sure what the rules are in Canada and whether the chains I've described, or those for sale, meet regulations. I've seen them all in use back east.
