I just wrote up a post on why i love wordpress and the basic features making it better than Blogger. Ya both are free to use softwares but there are many differences, 5 of which i tried to explain. Check the post - Why wordpress is better than blogger Hope you like it and share your views
Its an OK post but there a couple of problems with what you have written which isn't necessarily correct. I'll point out the ones I mean. 1) Ownership. You can redirect a blogger site to a custom domain. I have a couple of sites which are like this. 2) Dead blogs. Hardly any blogger blogs go dead. If they do it is usually the owner who did it. 3) Categories. What you have written doesn't make any sense. Anyway blogger blogs can have labels which do the same thing. 4) Plugins. Hands down wordpress wins on this one. 5) Pings. You can ping blogger sites. If you use a tool called pingoat it does exactly the same thing. Blogger is actually better than wordpress in a couple of areas such as free hosting. You can't beat free. You can pound the serve all day and it would still survive. Wordpress you have to be careful as it takes up so much resource space and CPU that any large amount of traffic usually kills it. Its an OK post. But I still like blogger.
Yep i know am not that good at writing stuff, but i know the brand of having a blog with wordpress is higher than that with blogger. Dead blogs is an issue which i see often in many webmaster forums actually. Wordpress is risk free. Pings - There is no automatic pinging method with blogger.
I don't think I've ever yet seen a Wordpress enthusiast who understands that you can host a Blogger blog on your own website just like you can with Wordpress. They all imagine that the choice between using the free hosting service (with all its limitations) and hosting it yourself applies only to Wordpress.
Blogger is great for the newbie who just needs something basic. Wordpress is more feature-rich and can do things that Blogger can't.
Blogger is great for a quick and easy blogging platform, but WP blows it away in terms of features and potential. The plug-in functionality alone puts WP in a different class of blogging tools above Blogger. As more and more developers continue to create plug-ins, I suspect that WP will become the Cadillac of blogging platforms in the next few years. I've tired Blogger and a few paid platforms like Typepad. I keep coming back to WP as it gives me the most bang for the buck (free). Just my .02 worth.
