Those are all terrible brown townogies. These are hosting services, not discrete products.
Here is a slightly better one: They are like the utility companies you purchase your electricity from. There is little difference in the quality of the electricity you are provided but one company has their billing-payment office on the rough side of town where you're afraid to park your car and alterations to your contract are made through the homeless guy sitting outside. Oh, and the competitor conveniently provides your cable, phone, and internet services at no-charge to you.
