I use the aptana editors for css and js - not for php cause I like the PHP Tools folding feature.
With eclipse I don’t dare to uninstall plugins…
I have EasyEclipse on my Windows XP box with the Aptana plugin, which installed flawlessly. Aptana have produced their 1.1x version recently, both stand-alone and Eclipse plugin, I think anyone who hasn’t looked at Aptana recently will be pleasantly surprised just how far they have come.
The main point of this post is to say, that with EasyEclipse and the Aptana plugin, I fell I get the most of both worlds, I almost feel invincible, though I do keep Notepad++ handy for that quick-to-edit and light-weight feeling.
