dot notation vs method which is better?

I'v was watching the Blog app tutorial today. (Modifying the Master Detail Template) at 10:58 it says that we can use either use dot notation or can be called as a method.

self.titlesArray.count;

or

[self.titlesArray count];

My question is what's the difference? and which one is better?

What is the difference?

Generally dot notation are used for accessing properties and method notation for calling actions.

Just to throw my two cents in. In the video Amit mentions that the method notation should be used for readonly properties. For example "count" is a readonly property hence the use of the method notation instead of dot.
