There are other papers and threads on this topic, but here is my 2 cent again:

There is a very strong advantage to having a chain couple the 2 motors and the 2 (or 3 or more) wheels on each side: when a wheel if off the ground, the power from both motors is automatically diverted to the wheel (or wheels) that are still on the ground.

2 wheels each with its own motor with out a linkage such as chain between them saves a bit in weight and packaging (potentially), but when a robot rocks you back on your hind wheels during a pushing match, that wheel out in front that is off the ground is not doing you any good.
