Coils have been around for many years in the front suspension without problem. I see no reason they will suddenly fail just because they are on the rear suspension. I don't foresee one being more "reliable" than the other.
That being said, if you are buying new and want a lot of "cushioning" in your available payload, get the 3500. That will give you WAY more payload than the 2500 will. Just remember that the 2500 has the low payload simply to comply with the class 2B restriction of 10K lbs GVWR... not because of any mechanical deficiency. In fact, the rear axles on the 2500 with the coil suspension are rated at 6500 lbs, and the rear axles on the 3500 with leaf suspension are rated at 7000 lbs... minimal difference. That is the only difference between a SRW 2500 and a SRW 3500... the 500 lbs axle rating on the rear and 250 lbs axle rating on the front...
