The lsp with the blinded path knows the amount that is sent to you, but does not know where it comes from and does not know if it is the last hop, maybe I have expressed myself wrong.
The sender will never know where the money goes with the blinded path, but with the wrapped invoices the sender will know that it goes to the Zeus LSP but not the final node, but the LSP will know that the money is for you.
If you don't use any of this the sender knows which node the payment goes to.
For privacy "no data" is better than "permanent encrypted data". I do think LN is currently developing in a good way. Also more devs taking care of privacy is better. More competition is better than no competition.
I would use it, like I would use MWEB with LTC, and CashFusion with BCH.
I still would prefer to fund my lightning transactions with Monero.
But let's be honest. The main problem currently is not the privacy within the mentioned systems, but interacting with fiat surveillance shit companies that do not accept LN, MWEB or XMR transactions. The problem that hinders privacy the most is stuck adoption.
And without rapid adoption they will close the avenues for merchants. They bankrupt the small and midsized companies and dictate the conglomerates to only accept transparent coins.
