I'm kinda in the same boat. I've had subs for PyCharm and WebStorm both personally and through work for years. I don't think I'm gonna renew them when they expire. I'm finding more and more that the free alternatives are just as good now.
Latest problem: PyQt on Windows. There's no intellisense in PyCharm using the binary install of PyQt. Getting it working, as far as I can gather, requires grabbing the library's source, finding everything I need to build the source in VC2010 and then (hopefully) it works. I don't know, because after half a day I was stuck on build errors and said fuck it, I'm not putting this much work into something that should be simple. Fired up VS2015, installed Python Tools, it scanned my python modules and bam, intellisense out of the box. I've had this exact issue repeatedly over the years with different libraries in PyCharm.
VS turns out to be a great IDE for Python, and for web work I'm finding that Sublime Text is pretty damn good with the right plugins. Haven't touched Java in years, thank god, so I can't speak to IntelliJ.
JetBrains IDEs were the sweet spot between lightweight text editors and the clusterfuck that was Eclipse. As time has gone on, those lightweight tools now do most of what made Jetbrains products so awesome.
