Yeah LN is pretty sick. I haven't used it myself but I've watched videos of people using it and they hit the button and literally a second later (or less) the other person has received the money.
As a network protocol its got some tradeoffs and still seems to need work and improvements that will hopefully hide some of those tradeoffs, but in terms of being able to send cheap and instant payments with Bitcoin its pretty amazing.
Bitcoin base chain is great for storing wealth and moving money around and buying things on the internet, but LN makes Bitcoin work for buying things in person where you need that instant payment.
