I currently play the Tom Anderson H3 and H1 in a baritone Les Paul. Awesome pickups. Dark, clear, thick, and smooth.
Played the Lace Drop and Gains before the Andersons, and liked them as well. The D&G have a snarl to them which sounds awesome live, but for me they didn't record quite as well, and weren't as smooth as I wanted. Really awesome sounding, though, and fun to play. But for me, the H3 and H1 just have this huge, dark, massive tone that I dig even more.
Also, ignore the resistance values. Having switched back and forth between the H3/H1 and D&G sets to make sure I truly liked the TAs better (I love both sets), I can tell you beyond a doubt that the H3/H1 is MUCH hotter than the Drop and Gains. So much gain off the H3, it's crazy.
I also tried the H3+/H1+, but on my drop-tuned baritone LP with it's .080 gauge low A, the H3+ would blow out on certain low notes or when sliding between notes on the low string. It'd make a huge, standing-wave "whump" kind of sound unless I whisper-picked it on those frets. Other than that, though, the tone was mind-blowing. But due to the whumpage, I went back to the H3/H1.
Anyway, all three of those sets are aces. Tom Andersons bring the smoothness. The H3+ would be great in something closer to standard tuning, IMO. The H3 is ripping good for dark, low-down stuff, especially if you rock tunings lower than a sewer tunnel. And the D&Gs are the way to go if you want more snarl and grit. For me, the H3/H1 is ideal.
