I just bought an LS 4140. I already own a 32 hp Kubota.
I looked at a number of brands and one of the major decision criteria for me was dealer support.
It came down to TYM [Rural King] and LS for me. I love my Kubota but for the price and standard features I ruled them, John Deere out, and New Holland/Case out.
The dealer I bought my tractor from is 3rd generation owner in his early 40's [2nd generation is still around] with a complete repair shop. Their store was well stocked, full of various brands [Stihl, Husqavarna, Titan.... all quality brands] and their repair shop was organized and had some guys with gray hair working [along with younger guys].
Rural King selling re-branded TYM was just opening up sales from their store in my area [they have been selling tractors at other stores for a few years] and are going to build a shop [i.e., no repair facilities yet]. Cabela's and other box stores have gone into and out of the tractor business. I like Rural King stores and management a lot but liked the LS dealer's stability. Since LS also makes tractors for New Holland/Case I should be able to get non-warranty work. I actually paid a bit more for the LS over the TYM.
Others I researched but none had dealer support near me: Branson , Mahindra , Kioti
You'll find that many So. Korean tractor makers have their products re-branded and sold my 'named' companies.
I have a thread asking much the same questions as you, when I did my search, but it apparently has been archived.
