I've never tried them, but always raised my own meaties, through selective crossing of Heritage breed varieties.
Buff Orpington, Barred Rock, Brahma, Easter Egger, & Australorp are a few I have found best for meat when crossed together.
The birds also end up with a more Gamey taste, & smell like Turkey. But I think that also depends on the diet abit too. Flavor is something I try to select for too, with multi generation crosses.
