I'm with you in terms of productivity/results etc. I remember when I started with a new team that were all Eclipse. I gave it my all. I really did. No doubt much of it came down to familiarity but there was something about it that I couldn't jive with. It seemed to introduce concepts/abstractions that didn't need to exist. It crashed a bunch. There were more steps involved with everything. I had pick up after it. It was slow. Then I said, you know what? I can't hack this, I'm going back to IDEA. Suddenly it felt like I was in a ferrari rather than a trabant. Fully accept that a lot of that was down to me not being a particularly fast learner, that I was used to IDEA in the first place etc.

I'm happy to pay Jetbrains three times the amount I pay to continue with it. This deal is great for me because I wanted to use PyCharm and CLion, and have historically used Rubymine, and the amount I have to pay to have everything isn't that far off what I pay already.

I consider it money well paid to be able to be more productive. Understand other people feel differently... it's nice to be idealogically consistent and beholden to no-one. That's worth a lot to many.
