I’ve already used Cachy, but went back to Endeavour. I found Cachy’s “optimizations” to be a bit janky. At the time they enabled some items for ntsync that were clearly not ready for primetime.

Performance-wise, I compared the two head to head and found Cachy and Endeavor to be equally performant for gaming. Cachy just didn’t offer anything for me that Endeavor didn’t already do.

On top of this, I found Cachy’s packages to lag a bit behind the Arch and Endeavor repos, particularly in the Cachy-extras repository, and it ended up causing me issues with things I used from the AUR due to packaging conflicts (the old Manjaro type crap).

Cachy isn’t for me, though I get why people like it.
