Very happy with my Boyd Pinnacle wheelset, same hubs that come on the 55s you're looking at, the Quest hubs. Hub pulls off without tools for easy maintenance, has a somewhat loud, but not annoying sound, def has very quick engagement. I've put them through some pretty rough abuse on a few gravel races/rides already and they're doing great. I'm local to Boyd's shop, and have ridden with Boyd and most of his crew multiple times, they're def passionate about the cycling community. Lifetime warranty and crash replacement, similar to other big brands.

Speed wise, doubt you'd notice any difference in speed between any quality wheelset of similar depth.

Full disclosure, I won my wheels in a raffle, but wouldn't hesitate to buy a set.
