Steve your analysis is exactly why some of us simply don't inject other brands unless we are asked to suggest other brands. But to expand it a bit, is is possible that another brand or two are available locally but the original poster may have ruled them out because of:
A) Personal choice,
B) Low dealer quality,
C) Brand preference,
D) Resale values,
E) Cost considerations,
F) None of the above.
What many consider to be "troll activity" is when people who are brand boosters, with little real tractor experience, probably jsut bought their first real tractor, or perhaps their first modern tractor, perhaps no experience in the size of tractor being discussed, jump in and inject their brand when nobody asked about it. While it is good to be proud of a brand, it is generally bad form to force feed a brand down everyone's throats.
Fact is I still consider myself to be a newbie and I am still learning, and every brand has its strengths and weaknesses and I find out more every day. Guys like JerryG, cowboydoc, _RaT_, MikePA, Bird, MadReferee, Egon and a couple dozen others I didn't list are the real knowledge base around here and combined have a couple centuries of seat time in various brands and various sizes.
