I've known coders who would be lost without using a sophisticated IDE and who get stuff done, producing code that is clean, clear, easy to maintain, is well documented, passes all tests, and is generally superb.
On the other hand I've known coders who write code in vim and who also get stuff done, producing code that is clean, clear, easy to maintain, is well documented, passes all tests, and is generally superb.
The measure is in the work, not in the tools. The skills are not in how you produce the code, but in the code you produce.
Having said that, the very best coders I know don't use complex IDEs. But that's anecdote, not data.
