Well I currently do not like WordPress anymore, although I like the Calypso javascript stuff they are doing. When somebody offers me small WordPress tasks, I ask money for it and do the work though.
Just to give you an answer to your question(partially):
First off. You should not compare Laravel with WordPress.
Laravel is a php framework which you can use to build your own WordPress.. WordPress is a blogging platform.
WordPress is in the league of:
- Joomla
- Modx
- Craft CMS
- other stuff
Wordpress has a big list of security issues and daily sites with WordPress get hacked. That's mostly because of unsecure plugins. You should always update your WordPress installation and make sure you run backups al lot.
WordPress offers 2 types of objects; Hierarchical and non-hierarchical. They call them Posttypes. One can be nested and the other one can't. Out of these posttypes you can create your own. So when your site is mainly CRUD..then it might be better to use a CMS instead if building your own.
WordPress offers authentication and usermanagement out of the box. Also offers email settings, a mediamanager, loads of other stuff straight after the installation. Then you only need to add content, then loop all the stuff out in your theme.
So most of the work is done in the frontend. And yes, you can start straight ahead.
WordPress can be used to build the most freakish sites you can imagine. I once used the blogging platform to build a planning tool for a company that had to manage their people, the places they had to work and loads of reminder stuff and such.
I've also witnessed a site that was bootstrapped Half Yii / Half WordPress / Half Bearpig. A monster of a freak.
You should check out this: http://getgrav.org/ It's unrelated but it looks neat. It's a flatfile CMS.
Or checkout Craft CMS. Because that is a better solution(in my opinion) than WordPress.
...ok I can talk on for a while..but just wanted to give a push in some direction.
