I've tried quite a few sets of tapes (though only the blacks in the LaBella camp) but one important distinction to make, also the reason why D'Addarios are my favorite, is that they have a soft satin kind of finish to them. Most other nylon tapes (all the others I've tried) have a shiny finish that does actually give them a little bit of audible plasticky "clack", depending on your bass; more noticeable with single coils and generally brighter sounding basses. I would think a piezo would also emphasize the clicking and clacking.
The D'Addarios just feel and play the best to me. Surely a hair darker in tone than a lot of others, but they don't have the clack. That said, I may be the only one bothered by this, but considering they're one of the cheaper options, I'd say they're well worth giving a try.
I concur that the D'Addarios have a nicer feel than most other tapes, with a lightly textured surface. If you like those, you might love the Pyramids, which have an even more interesting texture and a sumptuous feel, albeit pricier. Unfortunately, IME they had too much bottom end, but otherwise a very nice tonal balance, so I keep thinking I should go back and EQ the bottom to give them another try.
The Pyramids are also somewhat stiffer than the D'Adds, comparable to the GHS, Fender, and regular-gauge LaBellas. The D'Adds are pretty loose, but IME a bit stiffer than the light-gauge LaBellas, which to me are downright floppy (especially the gold white).
I like the D'Adds pretty well overall except that to me the G is on the tinny side. Also, I've mostly tried tapes on my fretless, and the D'Adds have a nice woody tone there, but with not quite as much mwah as I wanted. And I'd say that, like most tapes I've tried, they're a bit scooped. On the non-scooped end of the spectrum are the LaBella copper whites, which are mid-forward in an idiosyncratic way that doesn't work for me, and to some degree the GHS set.
I haven't found the perfect tapewound (to me they all have one or more significant drawbacks), but right now I'd say the GHS is the best compromise, followed by the LaBella regular-gauge blacks, and then the Pyramids/D'Adds. YMMV, of course. And I reserve the right to change my mind tomorrow.
