I sell Mahindra and Branson, as well as Deutz-Fahr for the bigger stuff.  We go after the market hard and do great in our area, but I give a lot of respect to both JD and Kubota.  Mahindra has some old school models, but not as many as they used to.  There isn't a ton of profit in a low feature tractor.  So Mahindra has added quite a few premium models in the last 10 years.  I particularly like and sell a good quantity of their Japanese built models.  The quality is quite good.  And they source a good deal of the USA sold tractors from Korea, also good.  The larger Indian built machines that are simple and robust are a good value.  
I think the 80-150 HP market is a different ballgame.  Guys that buy tractors of that size often use them hard and often.  They are making a living off of them.  If you are putting a tractor into this market seriously, it better be good.  Kubota is pushing into that market, and it will be interesting to see how they do against JD.
