They're more discoverable, because typing in `object.` tells the IDE that you are looking for methods on the type of `object`. If the IDE is aware of extension methods, it can also expose them the same as instance methods.

Java specific: If you're looking for a static utility method, then `UtilClass.` will also autocomplete. However, what if the function you're looking for isn't in `UtilClass`, but `SomeOtherClass`? What if you don't even know whether a method already exists for what you're trying to accomplish, and it could possibly exist in multiple libraries? Your discoverability engine quickly becomes Google.
