NYGM Tonnage war is a gameplay mod, aiming for the 'drown yourseld if you die' realism.
GWX is an all-around mod making changes to pretty much everything, sounds, graphics, gameplay etc.
But like Mooncatt pointed out, it all comes down to the personal taste. Try them both and pick the one you like. With 5mbps connection it wont take long. :rotfl:
