Stay with Hibu if
Stay with Hibu if the website is the smallest part of what you are buying. Their pitch is one company handling the site, the listings, the reviews and the paid advertising, with a rep you can call about all four at once. If you are running advertising through them and it is working, moving the website out of that bundle can break the reporting you rely on — and a website vendor who does not touch your ads cannot fix that for you.
Stay too if you genuinely want a person to drive to your shop. Hibu sells through outside reps who meet owners in person. Some owners buy that way and only that way, and there is nothing wrong with it. GablePath has no field sales force and never will.
