Wordpress is far better than Joomla..... Not only as its famous and many themes are there but Wordpress is better due to its SEO features.....
There are many things where Joomla wins and Wordpress looses and vice versa....
Its up to you that whether you want to use wordpress or joomla

My Recommendation: Wordpress

There are many free themes as well as paid one too..... try the paid themes as they not only gives you a nice theme but a expert support option too!
There are many sites where you will get a nice theme for your site....

Curiously Waiting for you site
Hope that it will be soon available!
