I have been using both SBI and WordPress for years and have learned a lot from both.
I was happy to see that now anyone wanting to start a business with wordpress has this great tool to show them the way. You get the best of both world, wordpress is the best to create your content but the bizXpress is the best to give you the step-by-step.
If I wanted let's say to buy an offline shop but have no idea how or where to start managing the business, like how to deal with suppliers, what's the best way to market the products, etc I would be so grateful if the previous owner would explain everything in details and show me how.
Well bizXpress is that virtual teacher a person just starting out would need. In my opinion, it's not for the seasoned entrepreneur but for the ones that are new to an online business.
