While I understand the appeal of Wallet of Satoshi for newcomers, I would not recommend it, since it is a custodial service.

Looking at the on-boarding process I think "Phoenix" would be a better solution for end users willing to spend their sats (even though it is more expensive).

On the other hand, for small businesses that will mostly accept sats, I agree that wallet of satoshi can be a great tool to start with, since for that use-case channel management might be a big pain point.
