well for final users doesn't have a deep impact since containers abstracts from all these kind of things. But for example I see that if your application is going to have more than container, you would like to have same containers as based containers so Debian is a distribution more generic and spread across developers. But of course we are paying the cost of not being as light as Alpine.
On the other hand official images also offers the dockerfile so anyone can build its own image with his favourite distro.
