For one, Legends Sidious wasn't the one fighting Talzin in SoD, so there's your differentiation off the bat. Secondly, it's pretty easy. In Legends speed is generally a far more noticeable factor in fights between characters who are several tiers apart. You won't see anyone being speedblitzed in the movies or animations because in those sources Force Users are depicted as low-level superhumans. In Legends Canon, you have Sidious moving faster than hypersonic+ beings can see properly. That's essentially all it comes down to.
You're misunderstanding me. I said it's a direct contradiction not because Palpatine wouldn't be able to do speedblitz Anakin, because he would, but in this case, the novelization directly contradicts the movie, and considering that, to my memory, the canon classes still hold value in Legends continuity, Anakin's POV should be invalid in this instance.
For the other point, speed is also determined by power, and while it is possible for vastly inferior characters to be equal in speed with their superior, (Vader/Obi-Wan is an example of that) I find it very hard to believe that such powerful characters would be blitzed by Sidious, especially considering that Talzin wasn't.
More like Kolar and Tiin seemingly stood there like idiots, considering that Palpatine stopped after coming close to them and before cutting them down.
He could take Savage, but add the synergy the brothers are famous for and he's dead (again)

And Sidious was focusing on overwhelming them with lightning, I don't see the difference.
Also, as I've argued countless times in the past, it's much easier to defend against a telekinetic grip than it is to break one once it bypasses your defenses.
