Everything else being equal I prefer the mac app store. Unless its a big company I think twice about paying direct from the website. A well known company can host their own, its the smaller developers for the mac app store, but Apple changes 30%, its too much for them. However, the mac app store needs loads of improvement. eg regional settings restrictive, 30% is too much, app discovery, app restrictions, etc The mac app store has lots of potential and benefits but Apple is just not putting the resources into it.
