Socketing: Not worth it?

Which among the sockets are worth it?

Which among them are the best?

Personally, I think sometimes, you get really lucky with chipping that getting these sockets are just bonuses that you can do away with. But that's just me.

They aren't really game changing, are they?

Maybe if you're bored with how slow your weapon is, then you can socket it with extra speed.

But giving it extra attack, for example, it wouldn't matter much if you still have to hit the monster twice.
