You may gain privacy with this tools but you create tainted UTXOs. I used all that tools many years, LN was always a disaster for me, tried all ways, self hosted LN node with unannounced channels, than ZEUS with LSP etc.
As I said I was nearly a BTC maxi but gave up with BTC and moved on.
Monero is a way easier for me and I don't see any reason why I should use Bitcoin, none.
