Re: Micro USB differences
I use all kinds of micro USB chargers on my new nexus 4 (Blackberry, S3, HTC etc)
They all work fine for me
Re: Micro USB differences
They are the same but one might deliver less power than the other. Use the nexus 4 because its better but u can use the other one

Re: Micro USB differences
I think the OP is asking about the physical fit and not the electrical properties.
Pay attention to the fit of both of them and see if one goes in tight or loose. If they both fit the same then you will not have a problem but if it is a little harder to get the Motorola one in then you theoretically damage the fit of the receptacle on the phone. IMO it would have to be a very tight fit to cause a problem.
Re: Micro USB differences
They are both micro USB's so they are the exact same size and everything. welle xcept the inside thing. Probably can't use the Nexus 4 with the motorola but you can use the motorola cable with the Nexus 4 probably.
Re: Micro USB differences
All the USB are not the same size. I have found there are some that will wiggle in a socket and some will stick out and not go all the way in as the metal tip is longer than normal. These all seem to look the same until you insert them or look very close and measure them then they can be 1 to 2 mm different.
