In Homestead, there are two ways "to go mobile": WebsiteBuilder and DudaMobile. What are PROS and CONS for each?

I understand that with Homestead, there are two ways "to go mobile": building a completely new website with the new Website Builder, or using DudaMobil which helps to create a 'mobile view' of your existing website.  What are the PROS and CONS for each? Thanks everyonel.
