Christy, I've been using Google for over a decade now, so Blogger was just an easier transition for me initially. However, Wordpress has a lot more options for customization and expansion than Blogger currently does, but it can also be a little more complicated to use (depending on your skill level).
My boutique business in on blogger while my nonprofit is on wordpress (we use the WP platform for our full website, so it made more sense to integrate our blog into that).
I would play around with both (both accounts are free) and just decide which one you like better.
This is my personal one on blogger:
