Linux or Windows ?

Hi,

I would like to know if somebody knows what the best OS to install Jahia 
is. That means which is the most powerful between Linux (Red Hat 7.5 
Professional) or Windows (2000 server). Are there any major differences 
(performance, stability, reliability,...) or is this rather a question of 
personal "taste"?
The installation will be: 
Apache Http Server 
Tomcat
Mysql

Thanks in advance for your help

Frédéric
