Unity game for windows store or windows phone

Hello, I am almost finished creating my touch game and I am looking to deploy it on windows devices. However, I'm stuck with some things that are not discussed on the docs. From what I've seen, the best way to target all devices is to simply go to build settings, choose windows store, and choose universal

Therefore, if that's the best way to target all devices, then when should I even use the windows phone 8 setting? Should I use the windows store setting for tablets and the wp8 setting for phones? OR has the wp8 setting become irrelevant with the universal option?

Thanks
