There's two sides of the fence...
One side says the only thing the Hawse buys you is clearance and weight reduction. Any friction you can take out of a system the less ware and tare on the equipment and more power you can put to the load. Rolling friction is much less then sliding, thus the argument for rollers.
The other side says that you do need to be careful to keep your synthetic winch line away from the steel roller housing. If your vehicle is at extreme angles while side winching it is possible to cut the winchline on the sharp steel housing.
Whether you use a roller fairlead or a hawse fairlead you always need to careful that your line does not come in contact with sharp edges on your bumper. Looking at the bumper, due to the front recovery points, I would think that an argument for the rollers would be in the event of side pull winching situation the rollers may give the clearance needed for the recovery.
Ultimately IMO, it boils down to the personal preference of the owner and their specific set up and considerations to the weight recovery angles, approach angles, etc for their use.
