I see Blogger as more of a hobbyist platform - it works great for a lot of people, and it definitely has monitization options, but I simply feel that WordPress is superior in every way imaginable.
From my experience with Blogger, advanced customization is just not present. You get a few different themes, etc. but that's about it -- then again, I haven't gotten too deep into the platform because I just hated it from the start.
WordPress, however, has so many more features in the way of customization, themes/theme editing, soo many plugins, and overall better user/post/page management options.
I use the self-hosted solution, but the free WordPress.com service is great for folks who don't want to pay for hosting.
Very well said and I can't agree more with you on this. I think the fundamental difference is that WordPress was meant to be an Open source project from the very beginning where people can contribute on it's development. Where as Blogger remained pretty much locked.
Even though both platform was intended to be used by people but WordPress went one step ahead and made it available for self hosting site as well.
WordPress got lot more functionalities than any other blogging CMS.
I did try to use WordPress but never got used to it, so I tried Blogger, thought I wouldn't get used to it like WordPress as I heard that its changed, but when I started using it I found that its become a lot like Xanga now.
I'm using blogger because its user friendly and even if it free, I can still install cute blog templates and I can add personal touch on it. I've tried to use wordpress but, I agree with Dustzilla that its more useful for professional bloggers who knows a lot a lot about the technical side of it. :))
If I were blogging for a hobby, I'd go with Blogger. But if I were blogging seriously (i.e. keeping track of company activities, Public Relations, etc), I'd go with Joomla! Professionally built website with all kinds of extensions available to build a shop/FAQ/forum/etc.
