Compare the engine displacement. That might give you the answer to the different RPMs. Kubota may have to run the engines higher to get the same HP, with lower torque.
If you were happy with the Case, why would you change the brand?
The M5 is definitely out of the price range to call it home owner. I once sat in one to compare it to my 6430. I wouldn't change colours.
Last thought. I'm not sure about the Fiat power plant. But I think they get away with a fairly simple aftertreament system compared to Kubota. Orange I think utilizes both, DPF and DEF.
