If all you're doing is reading and copy/paste, what kind of menu options are you going for?
The Foxit toolbar is pleasant to use and easy to customize. It gives me one-click access to the following commands, with no searching required. I use these commands frequently when reading, copying from, or printing pdf files.
Open File (Sumatra has on toolbar)
Text View Toggle
Text Select Toggle
Print File (Sumatra has on toolbar)
Text Zoom (Sumatra has on toolbar)
I like the way Foxit works and looks. Version 4.0 seems to be free of unwanted addons. It's also quite fast. Sumatra feels archaic and I can't think of a reason why I'd want to use it.
