Lightning is cool and has good privacy but it lacks in larger tx size and in UX for self custodial solutions. Monero works perfectly for larger tx size and easy UX as bitcoin onchain. Is ok to use both I do. Lightning and Monero both have uses for example spending Monero is easy with cakepay, anywhere that accepts visa online you can buy a cakepay visa then plug into payment basically anywhere online. Lightning has robosats and LNMarkets and Nostr. Monero I can swap into Bitcoin or Lightning without leaving the wallet.
