500mbs vs 1000 fiber

Hello everyone, I am in a household of 4 with 2 gaming systems, 1 laptop, 2 tablets, 4 smart phones, and 3 Tvs that use livestream services. Implying most of these devices being in use.. is 500mb fiber or 1gb better for my household? Im not really sure anyone would download much of anything at once besides me on crunchyroll for offline episodes at work.
