is probably the easiest and more popular since Google owns it but WordPress
is definitely funner to use
You have more control over your blog, you can make it look more like a website and there's tons of support too. There is a bit of a learning curve with wordpress but if you're willing to learn then you should at least give it a shot.
There are programs out there that you can use to add feeds to your blog. There's RSStoBlog
(not an affiliate link) but it's a little pricy. I've never used it but it is popular.
There's also WordPressMassInstaller
an affiliate link
) with this program you can create many blogs with several niches and it will add the feeds automatically, it's pretty cool and super easy to use. I've created several blogs with this already.
Hope this helps, if you have more questions feel free to pm me.
