downside is that macromedia is slow in getting out bug fixes (unless it's something so serious that it merits a "hotfix"). at least with tomcat, if you want it, you have access to nightly builds.
You also have access to the source so you can fix it yourself if you are so inclined.
I use tomcat, although I haven't been using it for long. One thing I can say about JRUN compared with Tomcat is this: when I need an answer to a jrun question, I can usually get it within hours on the macromedia forums. it takes me a bit longer to get an answer on tomcat questions.
Between the ranch and the tomcat-users mailing list, I've always been able to get answers very quickly; sometime from the people who've actually written the code in question.
I haven't seen the Macromedia forums so I can't compare the two though.
Also, for the most part, Tomcat has been ahead of the commercial servers in terms of supporting the latest of the
servlet and
jsp specs.
