My kona paddywagon is sloped and built like a tank considering kona makes MTB's a good 80% of the time.
Decent clearance. You can run 32 randos with ease and I believe those run on the bigger side of things.
Not to mention they're not really hyped and should be had for relatively cheap 2nd hand or on clearance (yeah the newer models arent really appealing as far as visuals go).
