I don't use any of them so no war here ;-) 99% of my use of these apps is open something look at it and close.
My preferred format is text so I use vi, Gedit and similar. I can do even nice "formats" in those apps. If I need something in more colors then html email is more appropriate and universal. If I will need sometimes app, documents, presentations I will think more about GUI for LaTeX (with output to PDF) then any other app. Of course when you need spreadsheet then you must choose something but I do this stuff once a year or so with some small document. -- This message posted from opensolaris.org
