Yep, the basic oem speeddisc rims are not really up to clyde duty. I folded a couple of them before moving on.
"Best" is a hard one to nail since personal preference and riding style come into the picture. Also there is a best if price is no object and there is best bang for the buck.
If I were looking for good wheelset without giving an arm and a leg I would get a hold of one of the
B29 Foundation wheelsets. Still a wtb rim, but a much more robust model. XT hubs with a stout rim is a good start and handbuilt by a professional is better than machine built most any day of the week
Money is no object?
Hadley Thru bolt hubs laced to an appropriate rim:
bombproof - Salsa Gordo or Kris Holm
trail - WTB AM, WTB Dual Duty, Sun Rhynolite, Stans Flow
My current wheels are a mix of burly, mid-weight, thru axle front and thru bolt rear, and a bit of economy mixed in.
WTB front hub 20mm thru
Shimano Saint rear hub 10mm thru
WTB Speeddisc AM rims (26mm wide model)
2.0mm straight gauge spokes
Brass nipples
Pieced together for under $200 with some patience, online hunting, and self build
