Godaddy vs. WordPress Blog Platforms- Help!!

About a year ago I got into blogging. I decided to start a blog on one of my sites (hawaiiblog.hawaiivacationstop.com) and I used godaddys blogging tool to do that. About a month later I was told that Wordpress is probably the best blogging tool to use. I then started one up using wordpress (www.waikoloavacationrentals.com/big-island-info).
I put more content on the wordpress one and have since added entries. After starting the wordpress one I did not do anything with the godaddy one.

Here is my questions: On all searches, the godaddy blog shows up higher than the wordpress one. Is there something wrong I am doing with the wordpress blog? Is godaddy better to use?

Thanks!
