The difference between working on SS and EM pins is like the difference between working on the engine in a 60s car and a modern car.
With a carbed engine, you have to do a lot of fiddling to get things just so, same as an EM pin.
With a modern car, you hook up an OBD2 scanner, pull codes, and then you can track a problem down to one of a couple parts which you then replaced; with a modern pin, you can look online and find what parts normally cause issues and replace them.
Just different beasts. I find SS easier to work on at this point, but that's probably just because I have more experience with it. It's definitely not as intuitive in many ways, though.
