Slightly off-topic: Is Evans still the standard introduction to "modern" PDE techniques like weak solutions/Sobolev/etc or did something better come out?

I remember that I found it not so well written whilst in undergrad, but everyone I know used it.

Great read! Ngl, I generally like Dr. Cook's bite-sized approach to content: it's a quick read and you learn something new.
