rob, welcome to TBN. First, let me say that you need to go to MY HOME at the top of the page, click, and fill out your profile so that we have an idea of what part of the country you're in, and what type of property size. This helps the members give you better answers as others from your area can answer some questions better than we who don't live around you.
Secondly, without knowing what you need to do with your tractor, we can't give good advice.
Kubota, of course, is a much better known, and better selling tractor at this time than Branson, so, yes, parts would be less of an issue. But I don't know how many Branson dealers you may have near you, nor their ability to service what they sell.
Another thing, are you planning on selling the tractor soon after you buy it, since you bring up resale? Almost all brands will take a big hit if you try to sell them too new as new models and great financing can make a newer used tractor less attractive.
Of the two, I suspect the Kubota would bring more on resale right away, but with the inflation in tractors, almost any older tractor will bring good money down the road if it's kept in good condition.
Give us more info on what you have and need to do so we may better serve you. John
