Not much atm in terms of MH/s, nor workers, but I liked this pool a lot in the past: https://www.suchpool.pw/

It's one of the more easy to use and professional pools out there imo. I stopped mining because the payout I weekly get at startjoin.com
for holding my coins there is larger than I can mine myself.

You can easily set the Automatic Payout Threshold, Donation Percentage, etc yourself. Other pools were either too unprofessional, or in some cases
the complete lack of user interface was quite bothersome. Anyway, hope this helped.

Cheers
