Better.... I do not think so. In fact I believe the McCruise is probably more steady and even than the Rostra installed on a C-14.
For what it's worth, my friend Larry and I did an 8500 mile trip, coast to coast Canada and USA in two weeks, on matching 08 Concours-14's, one with Rostra (mine) and one with McCruise (his).
Anybody familiar with the entire middle sections of both countries...lol, knows there is a whole lotta flatness. We did tank after tank after tank with our cruise controls on. On flat ground, once we got them synchronized, the stayed together bang on, for hundreds of miles...neither one gaining on the other.
What I did notice however, was on long uphill grades, that the Rostra would slowly gain on the McCruise. I'm not talking much here...lets say, on a long uphill grade...maybe a mile or two, that the Rostra would gain two bike lengths on the McCruise. On flat, level ground, they would stay neck and neck, all day long.
Just an observation...nothing more. Like I said, for the most part, they would stay neck and neck even, all day long. Pretty neat, considering they're both completely different kits. One would assume that they'd each require periodic adjustments to keep the same speed, but I can say with 100% certainty, that they would stay together all day long, for the most part.
