However, original post asked about the Motorola Droid, which is another carrier.'s device.
The Nokia have a a really good camera
The Moto X Have a front camera an also take really good phones.
I will go with the Moto X because is my dream phone, but is she wants a phone for life time NOKIA is the best
I dislike Nokia's OS (WP), tho' Windows maps are better than Andorid. But Nokia has a very tough hardware built and Nokia cameras take amazing pictures, their cam software is impressive!
So it depense on what your sis's lookin' for...
