I was posting the same thing a couple weeks ago 😂
In short, for BTC, lnaddress and keysend. Each has trade-offs.
lnaddress is nice bc it lets people specify a human readable, username/domain "email style" reference, that can be looked up to get the wallet address. this lets people provide their lnaddress, and potentially change the wallet address it directs to later.
