I'm sure everyone has their favorites. Here's what I always install on everything. Although the type of essential plugin is more important than the actual plugin since there are so many good ones. I always make sure I have something to make sure editing is easy, spam is prevented, and the site is fast, and SEO
This is what I usually use to fill those categories.
Advanced TinyMCE and all plugins that enhance it that I might need.
Akismet - or something similiar.
Wordpress SEO by Yoast
I will be interesting to see what others feel is essential.
