I happen to own both types of pickups on broadly similar guitars - both on hollow body Starfires, one a Starfire V from late 1963 (same spec as a Bert Weedon), and the other a Starfire IV from 1966 (long scale, hollow body, marked 'special' on the label). The Dearmonds on the '63 provide a more 'hi-fi' sort of sound. Low output (not measured) but amazingly detailed, better for Jazz or fingerstyle. They have the most wonderful bass lift, even Travis-muted. The minis on the '66 are really punchy, less ooomph than Gibsons, but more clarity and touch sensitivity in my opinion. Mind you I play mostly in a pretty low volume environment. I use a Fender Deluxe 2 amp - 1982, 22w, 1x12, played mostly clean, and I love both pickup sets. Had Gibbo HB's on a reissue L4, and didn't compete with either Guild so sold it.
In short, both have distinct personalities - for me theDeArmonds take it for sheer character, but like I say I'm not much of a rocker.
