I've never heard of Flexpool till this year and somehow they are now "The best pool". I find Flex-pool highly dubious...
Well we were 10ghs until this year so no surprise.
We're in the top 2 pools along with Ethermine when it comes to long term 2 months profit according to the mining pools monitor bot on telegram along with multiple independent comparisons. There is a large gap between the top 2 pools and the remainder. This is honestly because most pools are doing things. Its kind of crazy how popular this is.
These two posts made it famous:

Scale: e-5 ETH rewarded/MH/s/24h.
TW: count of tracked wallets.
PS: I discount the #1 as Crazy had their database wiped after 1559 so their numbers after 2 weeks are likely not accurate.
