[PollDaddy Plugin] WordPress x Intense Debate

I just migrated from WordPress.com to free host, and installed both Poll Daddy and Intense Debate plugins on my blog.

After further investigation though, I found out that Intense Debate also has a Poll Daddy plugin.

So, I’m asking for people with more experience than myself.
Which is better:

1- Use both Intense Debate and Poll Daddy – WordPress plugins;
2- Use Intense Debate – WordPress plugin and the Poll Daddy – Intense Debate plugin?
