...not really an answer. Ultra big ball is again only adding more power, hokage Naruto even surpassed that with ease outside of sage mode, so its not some senjutsu-only magic technique.
Ultra-big rasengan is a senjutsu and is label as such in the Naruto databook. Only time I saw Naruto made a rasengan of that size was in the Boruto movie when he and Boruto made a Parent/Child rasengan. However one can chalk that up to editing error. Databook trumps all.

I dont see how Sage Mode is on par with Version 1 or 2. I can't imagine any of those Jinks being able to stop, let alone lift, a giant rhino. >.>
It doesn't take Sage mode to lift heavy stuff, example;
http://naruto.wikia.com/wiki/Earth_Release:_Earth_Mausoleum_DumplingNote I am not saying Sage mode doesn't make you physically stronger, I know it does.
However so does Jinchuriki forms,
http://naruto.wikia.com/wiki/Jinch%C5%ABriki_FormsNot gonna put super long quotes but here's something for the V1 section; For each tail produced, the jinchūriki gains an incrementally greater boost to speed, strength, and chakra.
Here's something from the V2 section; Entering Version 2 creates a great deal of energy, producing craters beneath the jinchūriki and destroying any restraints that might have been placed upon them beforehand. Strength, speed, and chakra are once again increased beyond the levels of the previous forms.
Now there isn't anything that actually compares the physical strength between Jinchuriki forms and sage mode, but i'm just showing that Jinchuriki forms do increase the strength of the user excessively.
But Warren is right this is getting off topic and becoming a Sage Mode v. Jinchuriki thing.
