Nonsense. The best pool is the one with the lowest latency to your miners, lowest pool orphan rate, best reliability, reasonably-frequent but not too-frequent payouts (no more than once per day; less is probably better), and lowest fees. That won't be the same for everyone.
Miners with more than
50KH/s 1KH/s know what you just wrote is BS.
My preference with Monero is no pool, just solo mine. This is with less than 1 KH/s
