Easily #1.

Fun, funny, action, romance, character development and fully immersed in geek history.

Also immensely rewatchable. It’s virtually impossible to watch an episode of Chuck and be in a worse mood than when you started.

Even has Community cameos.

Also great music

West Wing, Chernobyl, Westworld Season 1, Breaking Bad

I wonder why "best show ever made" always has contenders made in the last 30 years. You Bet Your Life with Groucho Marx was such a fascinating show, and had some of the most intriguing, raw conversations with ordinary people, ever. Not to mention Groucho's natural instinct for wordplay that just never failed him.
