Trigger Design Pattern

Hello everyone,

While developing the trigger the logic can be added in the trigger or can be included in the Handler classes and those handlers can be used in the trigger, will there be any disadvantages of using trigger handlers?

To the best of my knowledge, I have never heard of any disadvantages. 
I guess 1 disadvantage would be increased complexity, not having the logic self contained within the trigger itself. 
One advantage of putting the logic in a seperate handler class is that you could reuse the created function within other apex classes and triggers. 
As far as I know there is no disadvantage and can you use the method you prefer
