They are the same. The 650 is not compatible with either. If you never intend to use the remote, then just get the hub. However I think you're going to find that phone/tablet control gets old fast.

You can control a PS3 from any universal remote via a cheap ($12) dongle like a Nyko Bluwave. So if that's the only reason you're considering the hub, you can get by with just a common IR remote like the 650.

Also consider that an IR controllable BD player runs around $40, far less than any bluetooth capable remote system. In that case, you'd just use the PS3 for gaming, and no remote control would be required. The PS3 appears to be the main reason you have to resort to expensive control options.
