Scala editors

I have recently been asked, "Which editor should I use to write Scala code?" As of now the two real options are:

• Text Editor (Emacs has a good scala mode, TextMate has a good syntax highlighter too)
• Netbeans
• Intelli-j (So I have heard)
  

Eclipse support is currently terrible. The only usable version is the version based on Scala 2.8 which is yet to come out so be careful for now.

I think for all the IDEs the code completion is not 100% yet. Scala 2.8 has added several hooks into the compiler for IDEs so the support will be must better.

Scala 2.8 is scheduled for release end of 2009 beginning of 2010.
