ESL is really really good. Absolutely cannot be recommended enough. I’ve worked through at few times and it’s a great book to have on the shelf.
ISl is good but as it being an introduction book — the lack of higher order math wasn’t my favorite.

What I love about the book is how the topics are "connected" so to speak. The narrative within a theme is typically "let's look at problem P, here's technique Q to solve P, but if you thought about P slightly differently you would see something like technique R would also work, so let's talk about that now".
The level of math might be tough for a beginner though.
