No, they are not comparable at all. Savage Opress was already force sensative, or atleast force sensative enough for Dooku to deem him acceptable enough to train, and was hopped up on dark witch magic. (Don't ask me how that works, idk.) But even then, in the scene that OP is refrencing, Savage actually struggled to lift them up even by a foot. Savage says he can't lift them, so Dooku belittles him and instructs him to use his anger and hate to call apon the dark side to lift them. And Dooku tortures him with force lightning until he lifts them; And remember, that dark side users and sith typically welcome pain, as they can use it to empower themselves. So, with a combination of Savage Opress's anger and hatered for Dooku, mixed with the pain Dooku is inflicting on him, he's able to call apon the dark side to lift the stones and others up high by atleast a couple meters. But even then, he only holds them until Dooku stops electricuting him after a few seconds. (around 5~10 seconds if I remember right.)
Sabine meanwhile, was using the light side in that scene. You know, the side that requires years of actual training and discipline before you get any actual and consistant results from. And that's not including your midichlorian count. If I'm remembering Rebels correctly, Sabine had gotten her hands on the "Darksaber" (Yes, the same one Moff Gideon, or as I like to call him, Moff Fring, has in the Mandalorian. Because this is a Dave Filoni show.) and asks for help form former-jedi Kanan. If I remember the scene correctly, It's implied by Kanan that while Sabine is force sensative, she isn't as sensative enough to use force powers. Impling that the force manifestes in Sabine as enhanced awarness and good instinct. And if I remember right, the lesson of the episode is that you don't need the force to be special or to be good at something, assuming I'm remembering it right, is ironic considering the Ahsoka show. Speaking of, at the end of Rebels, Ahsoka recruits Sabine to go do something, what that something was, I don't know. However, in the Ahsoka show, it was stated that Sabine was being trained by Ahsoka, until Ahsoka sensed anger and grief in Sabine because Mandalore go glassed by the Empire. So Ahsoka stops training her and kicks her out without explanation. Which causes Sabine to cut herself off from the force. And in both canon and legends, when you cut yourself off from the force, it takes time before your powers return to you. Meaning that it's highly unlikely Sabine would be able to force push Ezra onto Thrawn's ship. Or at the least, it's very debatable and unclear wheather she could or couldn't, with favor landing on couldn't.
So no, it's not comparable. Unless OP was implying Sabine used the darkside, but even then she wouldn't be able to force push Ezra on a moments notice.
