I agree...I don't think there is one all purpose bag. Depends on where you are...do you have small children...are you looking to take it to work, or volunteer meetings? What colors do you wear... How much stuff do you haul on a regular basis. Do you need the option to put in on your shoulder...

Is the GP too casual ? I find it a good alternative to my Birkins, when, for example, I have to be out all day; the Birkin gets heavy, while the GP is just as roomy but very lightweight, also the handles are long enough to go over your sholder, so you have that option aswell. For me it's probably the most practical H bag I have.....
