Selenium Vs Zentest

I would like to know which one is better. Zentest seems to lack good documentation whereas
Selenium seems to be having good documentation. TIA

Different tools for different jobs. Zentest has a bunch of utilities
included, including view and controller specific test cases and stuff
like autotest and unit:diff. Selenium is more for "black box" ui
testing, where you can drive the test with pure javascript or ruby+js
or whatever.
