I bought my Kioti RX 7320 (73HP) after doing quite a bit of research. The first factor in buying it was price, and I make no secret about that. It's Kubota counterpart is about 20K more for the same options/features. And the Deere 5075R was/is close to 30K more for the same equipment if I remember correctly.
That being said, when watching YouTube videos of a LOT of firewood guys, and what kind of tractors they had, I noticed that a whole lot of them had Kioti's. I'm guessing that a lot of them bought theirs for the same primary reason that I bought mine, price. But the Kioti sure has some outstanding specs compared to both Kubota and Deere. More lift capacity out front as well as at the 3pt, standard self-leveling loader, power sync shuttle trans, standard rear SCV (only one standard, but I don't remember for sure, Kubota didn't come with ANY standard?), and the cost of adding additional rear SCV's on the Deere like I did on mine was VERY expensive.
As for reliability, well that remains to be seen as I only have 40 something hours on mine at this point. I'm hoping that it proves to be reliable over time, but we'll see. I haven't seen a lot of terrible long-term reviews on their reliability from anybody, which was another reason I went the direction that I did though.
