For business customers I would give /48 and home users who might have 1-2
subnet I would give /56 or /60.
Reasons:
- Business customers night grow where you have to provide bigger amount of
subnet - allow space for future extension -
- Home users - they usually don't know what is subnet. Setting up
different subnets in their SOHO router can be difficult. Usually the
simple 1 subnet for every device is enough for them. Separating some
devices into a separate subnets is usually enough for the most
sophisticated home users. If not then he can opt for business service....
Just my 2 cents....
