I've been mining on Luxor for a couple of years now mining multiple altcoins and recently Bitcoin and, so far, it has been a smooth experience with my ASICs.
Team is always responsive to any questions and usually fast to respond.
Bunch of documentation available and free access to their APIs. No other pool exposes the amount of data they do, important to be able to audit PPS rates and integrate with custom software / third-party apps.
I'm running a custom python script that pools data daily for my operations reporting. Also, they send me yearly reports with all my transactions to make tax reporting easier.
