As far as the privacy currencies go I'm not sure what else you would mine with a 1080ti right now. ZCL? About the same income. Zcash even worse.
ZCL may be a better one to hold and have more merit vs. XZC in the long term. I don't know. I don't claim to be an expert.

ZCL was just pumped x25, so IMHO it's time to sell, but not to hold, there are lots of other Z coins that wasn't pumped recently, I'm better will hodl them.
