A couple of months ago I made the same transition, going from Dominants to Superflexibles. The Dominants were absolutely gorgeous strings in every respect, but at eight months, they died literally overnight. I replaced them with Superflexibles, which I had heard good things about and had been meaning to try when the opportunity arose.
I am happy with the Superflexibles, although not "taken" with them like I was with the Dominants. The Superflexibles are bright, a pretty strong sound, and, for me, relatively bowable (I say relatively because for me, bowing is pretty darn hard no matter what string I'm using).
The Dominants were softer to the touch, responded easier to the bow, and had a more beautiful "organic" sound than any other string I've yet tried. None of the metallic brightness of all-steel strings. They also had a shorter lifespan, as I mentioned above.
The Superflexibles have a brighter, more metallic sound, as one would expect, and are not as bow-friendly as the Dominants. I would say the Dominants beat the Supers in all respects, except for expected lifespan.
The Dominants did seem thicker to me (I didn't measure them), so they took a bit more fingertip to press and a bit more effort to pluck fast passages when playing pizz. Thus I seem able to pizz the Superflexibles faster than I could the Dominants.
Comparing the Superflexibles to other all-steel strings I've tried (Helicore Orchestras, Pirastro Flat Chromesteels, T-I Spiros, Corelli 370F's) the Supers are near the top. Not quite as bow-friendly as Corelli's, but a stronger sound for jazz pizz. Pretty good sustain (which can be good or bad, depending on if you want sustain or not, the type of playing you do, etc.)
All in all, the Superflexibles seem like a good dual-purpose string, and I like them, though I wouldn't rave about them. I hope this was helpful.
