A standard object has a standard tab already by default. You control the visibility at the profile level whether this tab is visible at all. Custom objects, you have control whether you create a tab for that object or not as it's "custom". You'd have to create a Lightning/VF page tab if you'd like to do something completely custom at a standard object level through a tab.
