Kona Unit X vs Santa Cruz Chameleon
Both published charts held against each other, on the specs that decide what the bike carries.
The short answer
The Unit X takes frame bag space and price; the Chameleon takes dropper compatibility. Which matters more is your route, not a scoreboard.
Assembled from the differences below rather than written over them, so it cannot drift from the table. Every figure is the manufacturer's; nobody here has ridden either bike.
Where they differ
3 of the 7 things we can compare come out differently. The rest are close enough not to decide anything.
Frame bag space
245 cm² more on the Unit XFront-triangle area at the largest size, computed from stack, reach and seat angle. It is what decides how much full-frame bag you can run, and a frame bag is the one place weight sits low and central.
Dropper post
only the Chameleon publishes dropper routingA dropper cannot be strapped to, so fitting one rules out almost every seat pack and leaves rail-mounted bags at a fraction of the volume. It is a capability and a constraint at once.
From
$100 between themManufacturer's cheapest complete build. Every spec above belongs to the frame and does not change between builds of the same model, so the cheapest build of the right frame is usually the right answer.
Side by side
Including the rows where the two are level, because a spec that doesn't separate them is still a spec you might be checking.

Drawn to scale
Largest published size of each, built from the charts rather than illustrated. The front triangle is the part that decides frame bag fit.
