Short Term Rental Gurus - Which program to purchase first?

[Turner Cress]

I have come across a lot of gurus that seem legit recently and was wondering if anyone here has purchased any of their programs as I am trying to narrow down to just one program. 

Has anyone tried Humzazafarbnb, Tony Robinson, Robuilt, or Michael Elefante's programs?

Humzazafarbnb seems to be accelerating the quickest, so I am definitely geared towards going that route. Any advice is appreciated.
