I think that if you talk through the entire davening – start to finish – except for 10 seconds where you observe proper shul decorum, you are a step better than if you talked with no exception.
Not universally — but when it comes to the difference between during laining and between aliyos, then yes. It is no better to be silent during aliyos if you’re going to talk during laining. I feel very strongly about that.
