A:AnswerDo you always carry your phone? If so, get the GPS one and it will do literally everything that the cellular one does and cost you less.
Do you like to go for runs without your phone or work at a job / school where phones are prohibited? Or are you wanting to ensure that the fall detection works even if your phone was out of range? Get the GPS + Cellular. It will cost $100 more for this option and $10 per month through your cellular network provider. The constant talking with towers in the watch will eat the battery substantially faster as well.
A:AnswerThe Nike watch has the Nike run club app as well as some Nike-exclusive watch faces, and a more breathable band for working out.

The normal Apple Watch has a different band which is not as breathable, that is the only thing the Nike version is missing.

A:AnswerYes. The only difference between the regular and the Nike model is the watchband with extra holes, some additional Nike branded watchfaces, and a trial membership in NIke+ run club
