I use this set on a Chapman Guitars ML3 Bea Signature Baritone guitar. The very first time I played them on this guitar I thought wow thats a bright and clear tone. Never before have I had a strong opinion on strings (used D'Addarios, Elixirs, GHS, Ernie Balls and whatnots) but this is the first time I thought that I'm definitely getting the same set for this guitar when these ones get dull -- which has yet to happen. Put them on the guitar 2 months ago, played an hour or two every night and they still got plenty of tone left.
On a baritone these things will do C standard (which they kind of advertise being built for) or open-B (being BF#BF#BF#D#) or lower open tunings. I foolishly tried to tune a set to open-C (CGCGCE) and snapped a string, so wouldn't recommend it on a baritone. Would probably work fine on a normal scale guitar.
Overall I can really recommend them for a baritone guitar at least!
