Handbuild, the carbon laminates apparently aren’t that durable for everyday use, I think here’s an ultegra level wheel that uses an alloy rim if you want to go the Shimano route (I’ve got RS61’s as my spare wheels and R-550 as my spare spares, they’re perfectly adequate).
I’ve got handbuilts as my sunday best wheels, <1300g, tubeless and <£300, what’s not to like (durability of stans rims may be questionable)?
Depends what you want to use them for, if it’s everyday in winter then the lower end shimano are cheap enough to be disposable when the rims wear out in 5000miles or so, but Stans Alphas may only last ~2000miles in the same conditions, but do make for a phenomenally light summer wheel set, conversely the DA9000 wheels aren’t that light and would be horrifically expensive as winter wheels, and more sensible A23/archetype/open-pro based build would last longer and allow cheap rim replacements.
