Both are Good but if you are going to use WordPress in future so WordPress hosting will be on your first priority because this hosting includes additional WordPress features such as;
- WordPress 2.5x Speed Booster
- Advance Security Booster
- Bundles of WordPress Themes and Plugins Support
I personally like WordPress Speed Booster which can be the cause of your increment rank in search engine. This hosting package is designed according to WordPress flexibility.
In case of simple web hosting, this is not included speed booster and above mentioned features. Disk space, bandwidth, MySQL are the common things which every hosting company is providing but you need to see what additionally they are offering to you (Pro features). Try HostGator WordPress Hosting (Recommended By Us).
WordPress hosting is excellent only when you want to build your site on WordPress CMS otherwise for custom scripts Simple hosting is good for beginners. You also can install WordPress on Simple hosting but you will not be fully entertained with the above mentioned pro features.
Choice is yours
