Migrate from passenger with Apache to Nginx?

[cduv]

Hello

I'm actually using passenger with apache on a production site with very nice results. But I'm always thinking if I can have improvements moving to Nginx web server. I know that is not an easy and clear question to answer because it depends of the experience and the environment . But, Will someone recommend change from Apache to Nginx? 

Some arguments: Performance? Easy to deploy? 

One of the arguments of changing could be use the balancer options of Nginx because I will need to scale in the future. I know there are many other options to solve that but Nginx seems to be easy to implement.

My environment is Rails 3+Ubuntu.

Thanks for sharing your experience
