I think the one really cool innovation for magnetic plastic clips is just ease of adding things in and out to your wire runs. Massively reconfigurable. Even velco loops it's going to take a couple seconds to put things in and out.

It's a pretty niche use case, but they look cool, they're just priced way too high for my budget. Printing them would make a lot more sense. But given loops are supposed to be out of the way anyway, the Velcro works just as well, and it's not visible.

Honestly however if it were up to me every room would have an overhead cable run!
