I agree completely about learning math faster, or maybe easier. My thinking has been that now we have a much better scaffold to construct knowledge on. Calculus, linear algebra, proofs, thinking in arbitrary numbers of dimensions, etc. are all much more ingrained than they were in undergrad, and as a result you don't have to spend as much effort on the details.

I wish I could say I didn't forget things when I was was in university, but I still remember the frustration of coming back from summer vacation and having forgotten half of what we learned last semester.
