I have run John Deere for close to 20 years. John deere has more creature comforts, better seat, etc. than Kubota even though Kubota has stepped up their game in the newest series. JD tractors are well built and the dealer support is generally very good, the main reason I stayed with them. JD tractors also have more features designed for efficiency, like IMatch, Autoconnect, and their loaders come on and off more quickly than Kubota. I would describe JD as like the Cadillac and Kubota is a chevy or ford. My next tractor will be Kubota because they are built stronger, heavier components, more lift capacity, and they are simpler, with less frills and are designed to get work done, not aimed at rich estate owners to mow their grass like JD seems to be moving towards. Both will last years of commercial use if taken care of, but Kubota is definitely built for ruggedness where Deere is built lots of times for asthetics.
too much stuff
