Bless me with all your wisdom.
In order for contributors here to help you in a meaningful way, you need to describe your land, soil and tractor tasks. Your budget is useful too; as is inclination to perform your own repairs, rather than relying on a dealer.
The only useful information you have provided is 'best value', which probably means an open station, sparely equipped machine. It may mean lowest cost per pound of tractor.
Brands tell you nothing until a model is parsed. The prudence and experience of the operator, which includes keeping up periodic maintenance, as well as operating within tractor limits, contributes more to reliability than what brand is on a tractor. This is especially true of brands where the model line is made by more than one manufacturer in more than one country, then painted to match other like branded tractors, as in the case of Mahindra and Deere.
The Mahindra 2600 series machines are made by TYM. You will get more for your money if you just buy a TYM.
Kubotas are made entirely by Kubota. Deere and Kubota are tops at parts availability. Deere and Kubota have 65% (+/-) market share within USA in tractors 35-50 horsepower.
Branson is often the least expensive 35-50 horsepower tractor option.
