I think that the "don't focus too much on brand" thing is somewhat valid when it comes to a North American style cabinet saw these days unless you want a unique feature, of which only one brand has something truly unique. All of the current generations of saws have things like riving knives, very similar fence systems, essentially poor dust collection, etc., regardless of paint color. "Service" is pretty much only parts regardless with maybe some advice over the phone or via email/chat. That includes even the really expensive stuff out there.
