I’m not sure it’s the “best” way, but it’s a solid alternative, and receives rapid updates when YouTube moves to break things.

I’m using this all the time myself. There is no login to YouTube required and it supports adding subscriptions and doing everything important you can do on YouTube.
And the best part is no ads whatsoever.
I’m sorry but there likely never be a long-term alternative for free software such as this on that platform. Neither you nor the developer has much say on how to use it.
