I have the previous version of the streaming stick 4k (from 2018 I think). Is it worth upgrading to the 2021 stick or 2022 ultra, and if so which one? Both are on sale on amazon. The 2021 stick is $30 and the 2022 ultra is $80.
Guessing at the year doesn't really pin things down. Best to cite the model number, found via Settings > System > About.

The Ultra will add wired Ethernet, a USB port for media, and the ability to use a non-RF remote. It may also be a bit faster, and can support some high-end audio and video formats that the sticks may not.
