I have used both. I 100% prefer MBS Highway. I believe the cost is closer to $99 and not $199. (I hope that was a typo) as I don’t know if I would pay $199 but I would pay $99. Both services give you daily commentary on the market and how what is happening economically in our country and was as throughout the globe and how it is impacting mortgage rates both current and future. MBS Highway has way more bells and whistles in terms of tools, calculators, presentations to help you consult with your clients.
I hope this helps.
