It depends on what you are looking for.
The Cybernet shows have always been kick ass for networking and IMHO, they have the best panel discussions (yes, I am bias)
Intenext is a huge event....Too huge. It's a non-stop party and to get any networking done you need to plant your ass in the lobby and catch people as they go by. If you don't do this then it is hit or miss as you pass each other in a drunken stumble towards the next party.
Both shows have good and bad points. For me, it's all about the business and I get much more business out of the smaller shows plus the parties are still there and fairly well structured.
But WTF do I know? I'm just an asshole newbie.
