I used PyCharm for a while, and got frustrated at all the tons of things that it tries to do "smartly". There is a shitton of buttons everywhere, and I ended up using breakpoint() anyway because I couldn't figure out how the debugger works properly -- and it doesn't always work (e.g. it didn't break when I was using GPU, for some reason). I'm sure it's excellent, but I just can't be bothered learning all of that. Same for git/github GUI, I prefer atom's, it's so much easier to use.
