For me 2️⃣ has an advantage because of the OnClick annotation and also the ability to use it in any class like a ViewHolder for example

with 1️⃣ onclick is as simple as:

someButton.setOnClickListener {
    // do stuff
}

so arguably even easier than 2️⃣ ?

Separate method is better choice for me to not create a clutter on the onCreate method

@OnClick(R.id.some_button) fun onSomeButtonClicked() {
   // do something
}

but more importantly having the ability to use it in any class like a ViewHolder is a huge advantage for me
