To clarify, using a managed service provides huge benefits.

The costs will be the same (at least with our inventory)
All stays are fully guaranteed (zero chance of fraud)
You receive expert advice to make sure you have the perfect place- believe it or not, about 70% of the time we place clients at a different villa/vacation rental than they initially inquired about for better value, experience and standard.
Plus you have a free concierge service that handles anything you need and provides important advice and tips.
Lastly, should anything go wrong with a villa/vacation rental you have a the leverage of a company handling any issues on your behalf.
To say VRBO provides a better value is a bit misleading since you have zero services, iffy support, a service charge now that makes it more expensive than our options and frankly a gamble that it goes well.

I am not saying that you should avoid VRBO, but to fall into the thinking that you are getting better value or a deal is off the mark.
