Does anyone use Mutt with gmail or alikes today? Is it worth it?

Mutt was my preferred email client back in 2000-2004. But gave it up for Gmail web interface.

Yes, set up with Luke Smith's excellent mutt Wizard [0].

Contrary to the other point, having a local copy of my emails gives me a sense of security and I can set up scripts using normal scripting tools to move stuff around. `notmuch` is good, but actually I can meet most of my searching needs with a 'limit' filter.
