Household Vs Individual constituents

Hi,

After recently attending a Tessitura conference I noticed that a few centres I spoke to set their family memberships in a slightly different manner to how we are setting them up in my centre which raised a question for us on best practice. 

To give you some more information, within my own centre when setting up a family group on a membership we will set up a household first and then link in all members of the family together under the household account, so we have common shared information spread through the account.   However, after speaking to a few centres I 've come to realise that several centres don't use 'households' and only use the individual constituent type and then link in other members of the family group together through relationships. 

I would love to know how some of you are setting up memberships for groups and what you feel is the best practice and why you chose to set them up as either households or individual constituents.
