How Accurate is grader.com?

Because I noticed a couple conflicting information they recommends me to do, but it conflicts some SEOmoz recommendations.

Grader is an overview. Use the SEOMoz Web app for a much clearer picture of your site. Just curious what conflicts?

My apologies, actually I am still running my analysis, & I think I accidentally hit send before I was finished typing. And in fact, as I can see, I definitely prematurely sent. ; )
I promise, I will send any conflicting issues SEOmoz way.

I just trust SEOMoz guys information more than I do Hub spots spammy newsletters, & banners. I just really am needing to know how SEOmoz feels about them, and if SEOmoz trusts their guidance. When it comes to the Site Grader portion, with SEOmoz webinars, and suggestions, and tools, I scored a 95%, when 5 months ago, I was an 80%.
