Isn't it what works best for the individual? Nothing wrong with opinions, either. Many times they are spot-on.
However, many times errant opinions are taken as gospel without the individual checking it out themselves to draw a conclusion.
As far as Steve Huff- didn't he dump his Leica 240 for Sony A7 series cameras?
I'll say this, before I had to sell my gear some years back, it was all Nikon. Having said that, I can't say I'll be going back to them, except perhaps for a 35mm film camera...maybe.
I've been a fan of Fuji for years, waiting for them to have their day in the sun. That day has dawned, IMO.
