Do Check : Blogger vs WordPress Which one is best
Why i leave Blogspot ?
Blogger has very limited source for everything i were not able to change or customize it completely Google host is too much fast but it is under control to Google, we cant control or manage it, theme are on very large but very low quality templates there is no tags option for post it should have, but Google blogger have new improvement in this month they added custom permalink structure for blogger posts this is major concept of SEO (Search Engine Optimization), but this is not enough for seo concept. need open source. Blogger SEO is very limited.
How I decide to join WordPress ?
Before I am using many blogs like Technozan , Android Lego, Eathosting and many more i make, and when i used blogger i realized blogger has limited sources if we choose WordPress it has open source framework and there is many professional themes to choose and WordPress seo is friendly meta tags and seo keywords Plugins, unlimited of Widgets and many more.
What You should do ??
Its up to you what you can afford and how much is your skills WordPress is little difficult to manage. and hosting etc everthing a admin need to manage and control.
