Nobody is fighting, just disscusin about wheels, we cant even know how the other wheels perform because they arent advertised enough, and you dont see them being disscused much, in apart from the G27 which is disscused on a regular base.
They might not be as well-known yet, but I think Fanatec is doing an OK job at it though. They're working together with the developers of Assetto Corsa for example, and also with other developers. I don't really think Logitech does any advertising at all theirself? They're a big company already, and everyone knows their products already. However, I think this will change even more in the coming time, especially reading the reviews and stories from people that made the switch.
They dont advertise themselfes, thats true, but stores do it for them, i always see some discounts or great deals on Logitech wheels in this or that shop, but never saw one for the other wheels mentioned a few posts back, i think its the matter of shoppers demands,if tech shops offered wheels like Leo Bodnar wheel, or FREX, i think people would buy them and then the demand would be greater, and with that, people would hear more about those wheels. But we are entering a disscusion of marketing and advertisment now.
I think that's simply because Fanatec only sells from their own store. Not sure if that's the best idea though. Like you said, local stores bring a broader audience.
About wheels from Leo Bodnar and FREX, not sure about that. They are too expensive for the average joe and therefore not interesting for local shops or 'normal' people I think...
