Ok, I stacked 3 codes earlier this week based on the reviews I've seen here and on Facebook, I also watched the webinar replay and a few videos on YouTube.
I did not get Frase, so I can't compare, but based on another tool here on appsumo called "Labrika", I can say that MarketMuse is a great addition, and the two tools can work together, the first one for technical SEO, rank checking, competitor analysis, etc.. but MM is way superior when it comes to topic research and content optimization.
Labrika also has content optimization suggestions, and many times I find both tools agree on the same keywords and additions/removals, but MM comes when Labrika stops to continue the job. You will get more specific topic coverage and intelligent research that's better than TF-IDF.

I am satisfied so far after a few days of usage, the only thing I am hoping to see is the domain name limitation lifted in the Connect application, we, as freelancers and agencies, use these tools to work on client projects and even our own websites, I really hope this will be implemented in the near future.

Otherwise great job guys and 5 tacos from me.
