Call me crazy (well people do anyways) but I am one of the many people that prefer HC pups over the SC. Keep in mind I am talking with my experience with 4 string models.
My Standard 4 has HC pups and the 500k volume pot and it just totally kills. All the upper Treble, Lows and slightly scooped mids. It really punches up a storm and cuts through the mix as most Sadowskys do.
My Will Lee has SC pups and a 250k volume pot. Although it sounds great, it is not as sizzly up top. The mid boost set at (500Hz wide) does grind it up but, I keep wanting to hear that upper treble response I get from the HC pups.
After last night, A/Bing both basses and messing with all the mid boost settings at band practice, I descided I'm going to get the HC pups and the 500k volume pot for my WL. Again, the WL is a great sounding instrument but, the HC pups work better for me for my tone goals.
+1
HC's... deep lows, polite mids, upper treble sparkle
SC's... tighter low end, more mid punch, and a more aggressive upper mid/lower treble grind than the 'slightly scooped+upper treble thing.
Both 'are what they are' and both sound great... totally a 'tone goal' thing. I'll again say that I actually preferred the HC's in my alder/rosewood model, since the mids and growl seemed to be kind of already built into that bass, and the extended top end actually worked with the sweet sounding rosewood (Madagascar) board on that bass.
On the ash/maple... not so much. For me, too much lows, not enough mid definition, and a top end that sounds beautiful but tangles up with the cymbals etc.
IMO, and pure personal tone goals there!
