yer making a general statement in trying to quantify two completely different pickups, and that's near impossible. particularly with regards to "output", which is a word that shouldn't really be used in conjunction with passive transducers since these gizmos won't work without preamps and amps and That's where the real output comes. "output" with passive pickups is part of its tone definition - the more wire that goes around a bobbin, the less treble and the more midrange and "output". for the most part, given the same "output", the 43/3 will not be as "fat" as the 42/5 - there are exceptions, but this is the norm. you will probably best be served with a 42/5 well wound engine nestled in yer tele's bridge.
