Man if you use Makita tools really really well but your coworker hates your tools and does the exact same job but with Milwaukee, does the customer care?
So really, who cares. Tools are tools.
For some people, Linux is their hobby. I wouldn't dare say someone's hobby is bad even if it's not for me.
I use Linux a lot for robotics. I use windows a lot for sysadmin at work. I need both and both work and get out of my way. Ultimately it's the things I do with my tools that make me consider their value.
It's like the difference between someone preaching and someone who does. Words are cheap. Actions speak louder than words. People who talk about one or the other should have little influence on your consideration of an os. People who get stuff done, the stuff you want done. They're the ones you watch.
Omg there's too many cars I can't buy them all.
