I agree one needs to make an informed decision and folks such as REMCO should not be used to make that decision. As the "towing experts" I find it interesting that backing is a con to dollies, however, on their web site backing is not listed as a con to tow bars. Seems rather biased to me.
An experienced driver that can back a trailer can back a dolly enough (short distance) to get out of a jam
if the dolly has a stationary bed. If, however, like my Master Tow the dolly has a rotating bed it cannot be backed any distance without possible damage to the dolly. Trying to back a rotating bed dolly, even one foot, could cause the bed to try lifting off the dolly structure at the rotating pin/bolt.
Next, as to the strong back some have mentioned, a trailer jack installed on the dolly makes that a non-issue. Although not recommended, a good trailer jack can possible be used in a pinch to disconnect the dolly while the car is still loaded. Doing this however depends on the tongue weight of the dolly when the car is loaded, the position of the car's front wheels in relationship to the dolly axle and buying a properly sized/rated trailer jack. This is no different than disconnecting a loaded trailer from a pickup truck. Here is the link to the trailer jack I installed on my dolly.

One additional note, as to the effects of towed vehicle sway, on my dolly with the rotating bed, any time the back end of my towed vehicle begins swaying due to heat related ruts on asphalt highways that sway is transferred to the rotating bed on the dolly and is not transferred to the trailer hitch. The wheel positioning of the dolly (at least one foot wider on each side than the car) will oftentimes allow the dolly wheels to skirt the ruts with no sway impacting the drivability of the coach.
Want to have some fun. Go to a REMCO dealer and ask them how they can configure a 2015 Honda CRV for towing. After they tell you about adding a trans pump or whatever else they will have to do ask them to see their assumption of liability for power train warranty repairs. When they tell you they don't do that, ask them to see the formal letter from Honda stating that their modifications are factory authorized and will not void the manufacturers warranty. When this cannot be provided ask them to see their sales contract and look for the disclaimer that says they are not responsible for repairs to the drive train in the event of a failure. Then ask them why they would need that disclaimer if their components do not violate manufacturer's warranties. About this time you can expect to be escorted out of the building by security personnel. If not, this next one is sure to work. Ask them to show you how that tow bar and base plate can be used to support the front end of a vehicle while you are performing undercarriage repairs, an oil change, or inspecting an exhaust system.
Again, make the decision that is best for you but make that decision based on facts and your preferences and not on someone else's biased opinion. Above all remember, a dealer does not realize a labor profit from the sale of a dolly, they do however realize that labor profit from the sale of a tow bar setup.
