I hate Deere because they won't give out information for independent shops and equipment owners to work on Deere Equipment. Plus, I grew up on a red farm and just never cared for the attitude of green guys. Unless you know some die hard JD guys, you wouldn't understand. It's a "farm thing".
Deere says they are at the top, but they have done a lot of things on the back of other companies too. Deere didn't invent the rotary combine, they copied IH. Deere didn't invent track tractors, they stole Caterpillars design. Deere came out with a really good series of engines in the 90's. It was a joint venture with Detroit Diesel. The 60 series Detroit engines and the JD branded engines are exactly the same.... hmmmmm. Anyone who doesn't read into Deere propaganda sees through their marketing. They may sit at the top in sales, but that doesn't mean anything. Ford has claimed to have the best selling truck for what like 30 years? Not the best truck, but the best selling truck. Well yeah. It was cheaper.
I hate Ford because they make cheap junk and it's hard to work on. Nothing they build is built to last. Nothing they build is easy to work on. Anyone who has worked on automotive equipment will agree, even Ford guys. No, things are NOT all "pretty much the same" now. There are still lots of differences inside the parts you can't see. I am a very well rounded mechanic, that's how I know Ford isn't any good. Everyone is entitled to their opinion for sure. But you won't find any blue ovals in my stable.
