We just chose the Blue Ox Avail tow bar. It is easy to set up, does not bind when unhooking and has a baseplate that is inconspicuous on our CRV when not in use. For a braking system we chose the SMI Stay and Play duo since it is hidden, only needs to be plugged in to engage and uses both brake lights and deceleration to activate. We also installed a fuse master so we don't have to pull fuses when the CRV is being towed.
I was very happy with a Reese fixed arm A-frame towbar on my Jeeps for many years. Then, because I needed more than 5000 lbs. capacity, I got a used Roadmaster Stowmaster 6000 lb. capacity telescoping arm unit. Other than the added capacity and the fact that it folds up on the front of the truck, I am not impressed. In fact, I use it just like it was a fixed arm unit. It is easier that way, for me. But, I bought it, and the truck is set up to use it, so I'm stuck with it. It works, that's all that is necessary. IMO, there quite simply is no "best"! there is only what each individual likes. Good luck in finding one that YOU like!

As mentioned, this is like which is better...Ford or Chevy. All depends upon what the replier is using.
Personally, I don't think you can go wrong with either Roadmaster, Demco, or Blue Ox. They are all equally efficient and all cost about the same. Best to buy the same brand tow bar as the brand of your base plates.
As for brake systems, there are many different types, so you'll need to do some research and decide which "type" is best for you. Then you can research the "type" you chose and pick the one of that type that suits your needs.
