So... It's better than a cable?

It depends.  

If you somehow manage across a Cat3 cable (10Mbps), Wi-Fi on this will be significantly faster.

Cat5e should the minimum requirement for any cable run.  At that point, speeds are going to be pretty negligible and the primary differences you'll see are with latency and ping (wired being slightly better).
