As people like Mechanic have explained on podcasts Ocean is a pool where you go if you generally agree with their ethos around "spam minimized" or "data free" blocks but it requires you to be able to accept more variable payouts because some days Ocean finds multiple blocks but some days finds none. For miners relying on "cashflow" that can present a challenge if they have bills to pay for hosting or electricity etc. but the pool has a stretch of lower block finds. For someone running some equipment at home or in the garage they might not have a problem stomaching a few weeks of low earnings because it usually averages out in the end before they go bankrupt.

I know when I mined at Braiins it was basically a flat line of earnings per day that only changed when the difficulty was adjusted. You could predict almost to the sat what you'd get. With Ocean it's frankly all over the place but as mentioned, tends to average out when you look at it over say a 30 day timeframe. I find the overall earnings roughly the same but I'm only running some dinky home mining equipment. Perhaps it would be different if I had a warehouse full of S21's or something.
