Price as turo, without having to pay the private parking lot and no walk. The rental companies are literally right across the street from the terminal. Easiest rental car experience I've ever had. If the price is close, I'd go with a rental company. If it's a big difference, go turo.
I've used turo, but you do run the risk of the car not being available if it's a private party with only one car and it gets in a wreck the week before you need it.
