- Implement recent JSP and Servlet standards
- Can easily run .WAR files
- Are pretty fast when serving content (speed comparisons on the web show only minor differences)
- Jetty uses less memory
- Jetty seams more "lightweight"
- Tomcat is very well documented - Jetty Documentation is sparse and targeted towards Java developers. The Jetty config file is (intentionally) like coding
- I know Tomcat by now
