Kodi Add On’s & Repositories: What’s Useful, What Not?

Hello.

I am new to Kodi. Installed on my Firestick, following troypoint instructions.

Subsequently, installed several video & repository add on’s following instructions from a YouTube tutorial,

To my knowledge, this tutorial does not include sketchy third party content.

I had wanted to list the add on’s, and solicit useful information about what to keep & what to delete.

However, I am wary of infraction, and will not do so at present.

I would greatly appreciate any feedback relative to the veracity of the link above. Are these useful add-on’s, or would I be better served elsewhere. If so, where?

Thank you,

GH
