Although I like WordPress, it is bloated for just a simple blog. This is one of the reasons I've gone back to using Ghost as my blogging platform. Another reason is the fact that I'm using JS in my daily job, so I just as well stick with it in my spare time.
Migrating from WordPress to Ghost was easy. Just install the Ghost export plugin on your WordPress install, and follow the instructions. You also have to update your posts images, and upload them to your Ghost install. After that you are home free!
