It is ok because it is free. I got crash only once in the three hours usage.
The benefit to try the latest visual studio is to get good impression in job interview i.e. as expert level programmer or good learner willing to try new stuff Also if you have nothing else to say on interview for yourself, by mention about latest visual studio you can always say it got n-bugs just like previous post
For me, I have used Visual C++ 1.0, Visual C++ 1.5, Visual C++ 2.0, Visual Studio all the versions with visual studio 2013 ultimate preview
yes it helps. The only shortcut keys I use most frequently is my customized Ctrl+/ -- search in all files, so to figure out who are those fucking one call a certain function.
