The Linkup is economical enough that I thought "why not?" and gave it a try. Not against top tier cables, I have Wireworld Chroma. Spoiler, the Chroma won. The iMac slowed a bit, the TV picture degraded and digital lost my interest. Just one persons experience. I switched back after a few days and everything blossomed.
I don’t have fiber. Download speeds are 200 wifi and 300 wired, either cable. The TV and streamer are wired to Orbi satellites. iMac is wired to router.
