Should I use Custom helpers in Laravel instead of simple static methods of a class?

Helpers:

We add arrayhelper.php to App\Helpers folder Then we add

"files": [
      "app/helpers/arrayhelper.php",
]

to section

"autoload": {
}

in composer.json.

Now it's possible to define methods and use them globally.

Static methods:

make class ArrayHelper define static method (e.g. doSmthg()) and then it's possible to call it like this ArrayHelper.doSmthg()

Question:

if there is some benefits (e.g. better performance, less memory usage) of using helpers in Laravel or it's just matter of habit? How about overlapping of methods, e.g. I have to add() methods in different helper files. If I use static methods, it's solves the problem:

CustomClass::add()

and

CustomAnotherClass::add()

How to choose between helpers and static methods?

P.S. There was some similar questions, but I read through all answers and I didn't find what I exactly wanted to know.
