class b less than 20 feet

Just kind of wondering why some have jumped from the Class A to the Class Bs and why? What Models, Options did you make the leap too? Don't want to hear the Spouse did not like the Class A or is was the cost of fuel What will you now do differently?

Looking to buy Class B less than 20 feet, we are looking at Aktiv (maybe buy when dust settles after audit) , but appreciate feedback on other models.
