I was once brought in for an interview for a Unix Systems Administration job. The ad said they needed someone with experience with Unix administration and knowledge of basic shell scripting. I got an interview with an HR person and it went well. I stressed my extensive experience with Sun Solaris and Linux. She sounded very positive. A couple days later I got a call to come in for an interview with the IT manager. I arrived a bit early, dressed to the nines in a new suite. I was kept waiting for over half an hour and when the IT manager came into the interview room, he gave off the sense of wanting to be anywhere else but there. He asked me how many years experience I had with IBM systems and AIX. I told him that I had very little experience in these areas. He said, "Well I need an AIX admin. You are obviously not qualified. I'm sorry, this has been a big waste of time." He then marched out of the room without so much as a handshake or a "nice to meet you", cursing the HR staff. It lasted all of 1 and a half minutes.

There are many different tools out there that allow us to do the same job in many different ways. There is a very good reason for this - we are all different! Each of us see things in slightly different ways and therefore use tools in different ways. The best IDE or tools, if you like, are whatever works for you and makes you productive. All this arguing sounds like a lot of, "My tool is better (read: BIGGER) than yours!". I'd like to think we've advanced beyond that point by now as a civilization. Now, to answer the original question, I use vi, emacs and scite, depending on the platform and project I'm working on.
