By all means please use whichever editor you like. However if you want a recommendation then use
Sublime Text 2
If you are using Sublime text 2 then I have created a LispyScript Syntax highlighter for it. It is not a complete package yet, so I have not created a installer for it. So you have to install it manually for the moment.
1) Create a folder 'LispyScript' in the sublime text packages folder.
2) Copy the file 'LispyScript.tmLanguage' into the folder and restart sublime text 2. The file is available here.
