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....
