In order by output, as inferred by the resistance
STK-S4 Stack Plus, 9.62k neck, 10.36k bridge, 4-conductor, A5 rods
STK-S7 Vintage Hot Stack Plus, 11.97k bridge, 3-conductor shielded, A5 rods
STK-S6 Custom Stack Plus, 14.45k bridge, 3-conductor shielded, A5 rods
STK-S9B Hot Stack Plus, 20.26k bridge, 3-conductor shielded, A5 rods
STK-S2 Hot Stack, 13.2k neck, 20.6k bridge, 4-conductor, Ceramic bar
STK-S10N YJM Fury neck, tapped 12.20k, full 25.45k, 4-conductor, A5 rods
STK-S10B YJM Fury bridge, tapped 12.83k, full 25.65k, 4-conductor, A5 rods
I believe the Stacks have some equivalents in the regular single coil line (Mincer or Jeremy or someone else should correct me on this, I only have experience with some of these pickups, not all...)
SSL-1 / SSL-2 = Stack Plus (STK-S4)
SSL-3 = Hot Stack Plus (STK-S9B)
SSL-5 / SSL-6 = Custom Stack Plus (STK-S6)
...or something like that. Someone else might have a better/more accurate comparison list.
The lower output ones sound Fendery. They sound like normal singles to me without the noise.
Coil tapping makes them weaker and not noiseless. Only useful if you are going to combine that coil with another one, like one coil of a bridge humbucker and keep it noise-cancelling.
The STK-S4 is the typical SSL-1 Fendery single coil sound. Some people prefer a little hotter bridge to balance better, a la David Gilmour SSL-5. I believe the STK-S6 is that equivalent. The other bridge options are even hotter. But the hotter you go, the less Fender Strat sounding things can get.
