I use both on a daily basis, and VS + Resharper beats the crap out of IntelliJ, IMO. My opinion might be different if I had to pay for my licenses, but independent of cost, VS wins.
When I tried the public preview, my heart sank when I saw that "Store" icon in the start screen.
The new UI I can deal with or customise - I've been developing since DOS, I'm sure I can get used to it. But please don't remove the very reason Windows became so popular: a relatively open ecosystem.
As a result of that (and the destruction of VS), my personal projects are no longer under Windows, and my career is also shifting away from it.
I'm not anti-MS - I was once their biggest cheerleader. I just don't like their direction.
If having a store inside windows that becomes popular enough, there would be potential for windows to become free to install/use.. (hey pigs could fly) Would that alleviate concerns about it?
