I use mostly CLion, PyCharm and Android Studio from JetBrains. I get what you mean, but about depth and getting really good with a single tool, most of time I have more success in this with command line tools, as their interface almost never changes, the knowledge can pile up in little steps. With graphical UIs (hi Xcode) I mostly don't see big benefits of getting that much of depth as productivity gains can be swiped off by software updates - or alternatively, by switching projects with different technologies.
