S stands for Stout!
I'm running two of the early style (prior to 93) S-10s, with a third coming online this year. Two short bed, standard cab pickup models and one four door Blazer. 4.3L V-6, auto in them, 3.42 gears, 3.73 would be nicer for pushing. The kicker is that I'm also running 8 foot plows, Series 25 Sno-Way. I know this will generate howls of indignation, but I'd put them up against anything esle with an 8' straight blade. The short wheelbase makes them ideal for residential or any other close quarters work. Personally, I'd stay away from the imports, they just don't have the weight or frame section for working. Before anybody tells me how great their import is, go measure the frame and weigh it. The S chassis is heavy for the size of the vehicle and quite rigid. The same light weight and flexibility that makes the imports so good off-road goes against them as a work rig.
