The Superhub 1 is like a small blade being inserted into your back from Virgin media.
The Superhub 2 on the other hand is just a smaller blade in your back from Virgin Media.
They're both pretty terrible I'll be honest and you'll only get the optimal experience if you just pop it in modem mode, of which it works fine doing.
Plus it looks awful
Super Hub 1 looks awful and ugly, Super Hub 2 looks nice to me from what I see in the pictures.
