Yeah! Wordpress is more user & seo friendly! it has thousands of free modules & themes and further customization Joomla! cant be easy to maintain for everyone
Wordpress is free web blogging application and joomla is free cms ( content management system ). Both are great but from my personal point of view, wordpress is better in term of appearance, admin interface, multi-user capabilities and flexibility. Additional, you can order a customize theme ( look more like a site, and less like a blog ) and your visitors will not recognize what kind of application that you are using.
I do belive they both aim at different areas of experties ... U really can't beat Joomla! when u need to set up a big & complicated website and wordpress is so easy to use, u needn't think elsewhere for a personal blog or a simple content website ...
It will depend to your needs. Joomla is a CMS that can provide e-commerce while Wordpress can be considered as CMS also but It has limitation. By the way What kind of website/blog your are planning to make?
