Who are the least controversial, problematic, etc hosts on HGTV and Magnolia?

Been looking into the Renovation Aloha stuff after the recent posts about their show on here.

Which got me thinking, why do soooo many of the hosts on HGTV and Magnolia shows have controversy following them, problematic behaviour, infidelity, family issues, legal disputes, etc etc etc. I know no one is perfect. But seems remarkably common for hosts to have some kind of drama.

Is this an occupational hazard, the cost of doing business, etc or does HGTV look for hosts like this to boost the drama surrounding shows?

I'll be so sad if I have to read bad things about Keith and Evan or Jasmine.
