I a big fan of the way Bob Nystrom skips the LR and LL theory and goes straight to recursive descent parsing plus the precedence-climbing trick.

I'm of the opinion that if you have to learn ONE thing about parsing then it should be how to write a recursive descent parser by hand. It is the parsing technique that you are most likely to use in a real project if someone throws a parsing hot potato in your direction.

That said, if you are on the mood to learn at least two things about parsing then there is no way around the LL and LR fundamentals. :)
