I was in the same predicament a few weeks ago. I looked at Kioti, NH, JD, Yanmar and Kubota. I currently have a JD 770 ( re branded Yanmar ) and it has been a really good machine. JD was at the top of my list due to this and there dealer network. The JD just costs too much money ( 36k ) for what you get. They want to nickel and dime you for everything it seems like too. Rear remotes, R4 tires, and a brush guard with the loader are not standard equipment.
The Kubota MX series are nice machines, but for 31k I'd expect them to have some bells and whistles such as cruise control, ePTO, rear remotes, and to not have turn buckles on the back to adjust the three point. I wasn't too keen on the treadle peddle also.
The Kioti NX4510HST was a nice machine but the local dealer was only willing to make me a deal on a machine that has been sitting on the lot for at least a year. No thanks. That kinda put a sour taste in my mouth about Kioti.
The NH ( re branded LS ) machine was nice but they don't have hydro stat in there higher HP Workmaster series. You have to jump into the Boomer series. The salesman told me they start out at 35k.
I ended up purchasing a Yanmar YT347 because it has some of the bells and whistles ( cruise control, brush guard, rear remotes, loaded R4 tires ) I'd expect from a machine in that class and I got one heck a deal on it. From what I was told and have read, Yanmar makes the machine soup to nuts. They are built in Japan and then brought over to the us to have tires attached, fluids put in and tested. I am not a fan of the styling but you have to take the good with the bad. Yanmar supplies diesel engines for JD and various other companies too. I also liked that the engine is a 4 cylinder non turbocharged engine vs a 3 cylinder turbo charged engine in some of the models I was looking at. Feel free to PM me with any questions.
