The MM is pretty up there, power wise, but nothing insane. The INF's are quite powerfull too.
More powerfull pickups, not just talking about BK here, will tend to overdrive your preamp sooner (duh!), have more compression, less dynamics but a more focussed, attacking sound, and its easier to get harmonics and legatos out of them. Some bad ones, stock and bigger brands included, get pretty muddy too, because wire attenuates high frequencies prefferentially, so the longer the wire, the more lows you get compared to highs. Actives (EMG, duncan, though they cant seem to figure out how to do it very well: live wires are some of the worst pickups I've ever heard) and scatterwinding (BK) are solutions to this, with their own additional tonal bi-products.
