this is quite an open question, but here's my point of view: with VS you get a true Integrated Development Environment which for me means:
- support a whole lot of languages
- is 'all-in'one', no need switching between programs
- great editor
- very great debugger
- very customizable and extendable, good macro capabilities, good integration with other products, rather mature in comparision with Qt Creator
The only reason I use Qt creator is becasue of the Gui designer actually, pretty much all other tasks can be done by VS.
That doesn't necessarily mean one is better than the other though, I'd just say one is better at performing certan tasks than the other. Use the right tool for each job.
