No. I upgrade my Ubuntus before they go EOL so I don't need ESM.

Most places that want ESM do so because they can't get away from EOL versions. I refuse to get stuck in that swamp myself, so I run LTS and migrate/rebuild them when necessary.

I'm running Ubuntu on a server. I've enabled the free Ubuntu Pro subscription to get ESM patches for the universe repository. Not sure if it really matters, but better safe than sorry.

I do. I upgrade before the major release goes out of support, so no I don't get much from it, but I do still get patches from it occasionally. Iirc they released an imagemagick patch before upstream did

I have enabled this on my private machine, because it's free and it was asking so nicely.

I don't have the same patches on servers at work.

I’ve tried it. Can’t really see much difference from not using it. As others have said, being a personal user you’re not much of a target - being smart about what you run on your computer has much more of an effect on security.

In the future I probably won’t bother

free security updates are a win of course

I am for my gaming rig!

I haven't tried it, but the live kernel updates feature is what intrigues me the most.
