Is The Walking Dead really 3x Better than American Horror Story?

This morning I was looking up the ratings for both season 5 of The Walking Dead and American Horror Story: Freak Show.  Not surprising was the fact that TWD beats AHS on a weekly basis, however what was is the margin of victory.  On average this year the walking dead beats horror story by 3x. 
So what that translates to is when 4 million people tune in to freak show over 12 watch the dead.  The one exception was the season premere where AHS broke every record in FX history ratings wise with 6.2 million people watching, meanwhile 13.5 tuned into walking dead.
In all honesty I do not think the margin is even close to being as huge as the general public are making it.  Yes TWD is a kick ass comic and by all means is a fantastic show that has even been featured at Universal Studio's Halloween Horror Nights for the last three years, but damn AHS is so well done!
As a matter of fact if you want to compare bragging rights Horror Story was actually won more awards than the walking dead!  It has become almost certain that one cast member will win an Emmy each year!
I don't expect the underrated AHS to ever catch TWD as long as zombies are as hot as they are, but there is no way the margin represents a true difference between the two.
