PPS is more and more what people want.

If it's good for the miner / pool operator has to be determined on an individual basis.

Personally, I have about $7.50 in dust left on Kano's pool since 2016. Due to PPLNS and the lack of luck, it's just a write off to me at the moment, never going to get paid and unless I put some crap miner on there when they happen to get lucky and find a block I'm never going to get paid. In terms of crypto mining losses it's a small one.

For smaller pools like Kano, PPS is looking to be the only way to gain more users. A small user might mine there knowing they will get paid what they mine (minus the fee) if they grow into a larger miner they might stay.
But, very few larger miners are going to move to or start with a small PPLNS pool.
