I would argue that not every distro works equally nor "good".
Redhat for instance, as per my system admin, tomcat6 (8 years behind) is the only version "blessed".
Right now I am at odds with my server admins because I want our code to run on something newer and more capable of dealing with issues I am facing, and they want to stick to redhat blessed packages.
As for the question, it should have been what distro is best/good for tomcat X, as each version of tomcat like each version of say Internet Explorer, are unique in many ways. A lot has changed in the past 8 years, and while security patches have been applied, tomcat 6 is out of date. 7 is only 4 years old (Good history and time for bug fixes, but new enough to take advantages of new ideas and technology), and 8 is new, maybe too new for some.
So for answering the question redhat is not a distro I would call good for tomcat, if I find the best I will post an update.
