Hey and welcome!
If you are used to EMGs, you won't find any of the BKP range (or probably any passive pickup) to have a more prominent "c--ked-wah" mid voicing than you are used to, and in most cases much much less.
-The Ragnarok has the closest similarity to the active sound in its voicing, with that audible vowel-like "c--ked-wah" mids (though less than an EMG 81 or similar), plus a really tight low end and smooth top but with the signature ceramic cut. These drive really hard so you get a compressed and "fun" feel, though if you are used to picking really hard you might find they're a bit on the gainy side (however, they are much less compressed than an EMG).
-Black Hawks are altogether more wide-range sounding with quite a flat midrange, and extended highs and lows. Ceramic will give you tighter tracking bass, so you get less resonant low end frequencies on palm mutes, and the overall response is faster reacting to the picking hand, and sharper in its attack. The Alnico option is slightly squishier feeling to play, and less bright in the top end.
That said, my main picks would be either:
-Miracle Man, for a really chunky but tight pickup with a great lead tone, and less compressed feel than the Ragnarok.
-Black Dog, which gives loads of mid growl, smooth top end, but the percussive and tight low end of a lower output pickup. Really versatile if you need to cover lots of ground, and has a killer high-gain rhythm sound too.
