I coded in IDEs for almost a decade up to that decision.
I could feel my "clarity" fall year for year.. I have never looked back.
I stand by my original statement, that for me, IDEs hinder my thought.
Also, I have seen other coders I really consider high-end having the same considerations (it might just be a bias, where I just notice those, who agree with me)..
Have you ever seen the "competitions" where they give a really really good photographer (or videographer) a 50$ toy and lets them compete against an amateur with a really high end setup..
Only amateurs blame their tools (above a certain minimum threshold)..
