I am a mac user myself and only use VS with Unity3D on Windows. But man, it has really turned my opinion about IDEs. Yes, even Jetbrains IDEs are slow compared to Sublime/vim but every time i have to explore a huge Api or framework to find out how things work i feel crippled by Sublime. For example in PHP i often need to know
- Which classes implement this interface ?
- What was the namespace of that class again ?
- take me to the definition of this (in a different file)
- show me uses of this function across the entire codebase
Yes you can also do all of that with some nifty search action in Sublime, but i don't think its as efficient.
When you work for example with a node or angular project that doesnt matter, i am happy with Sublime there, but i currently built a huge application on top of symfony2 in php with tons of third party libraries and in that case it just doesnt work well.
