Its always been a toss up with me. Physical means that if something ever happens to one of the companies involved I don't have too worry about maybe never being able to play my games again. It also means that some games that may need a slightly more capable machine could just have the parts added to them if they are a cartridge. Although if they break I have to either mail it in for a replacement or buy a new one altogether. Digital means that it takes up no physical space, and that I can put it onto physical media if I choose and more than likely still have it work fine. Downside is that I more than likely have to be connected to the internet to use it.
