Arnulfo,
I was working at Advance Auto for a while and they were the most requested by customers both over the counter and through the QPA program for commercial accounts, and they were the best shock for the price. Koni list an application but they require an adapter to work with the Riv, and they were that much more expensive. The "other application chart" for the Konis has quite a number of different applications from Avanti to Volvo. (Almost A to Z)
I cross referenced the Monroes and they only applied to Buicks from the era. I figured that had to account for something, at least it wasn't some Dodge truck shock that was similar in length that Monroe could substitute and pick up another application for a generic shock.
As you stated, I too wasn't looking for a performance shock just something to give the car a nice ride. At the same time, I replaced as many other bushings as I could find parts numbers for. I'm sure that this as well did a lot for the increased ride comfort.
Another reason was that it carried the manufacturer's name rather than the distributor's name. You can never tell what you get when you buy the "private label" stuff.
