Mareksays:
If a router does not have a matching IP route for the BGP route’s Next-Hop IP address that router will not know how to forward packets for that particular prefix, and the best-path algorithm removes such a routes from consideration.
If Next-Hop address is reachable the first attribute to compare is Weight.
(I hope, I will not get this one)

Sorry.
This next-hop is IPG metric to BGP Next-Hop.
