Value: Targus Wins
While the price of a TUDS may initially appear to be more than a proprietary dock, the fact that vendor lock is escaped with a TUDS enables negotiating PC/Macbook price savings. Also the TUDS is reusable with any Windows PC or OS-X Macbook while the propreitary dock works with only one PC brand, and sometimes only one model in that brand (only one device refresh). TUDS is the last dock you ever have to buy. And when there is only one dock to support, there is less user training required and less IT support needed.
Functionality: Targus Wins
TUDS work with any Windows PC or OSX Macbook and offer the features in its various models to cover more applications and usage cases than any other one vendor. The ACP71/77 also have the patent pending PC power and charging feature that no other universal dock can offer.
Performance: Targus Wins
TUDS connected at USB3.0 render up to two 2560×1600 videos at 60FPS, nobody else can. Also, the TUDS GbE port works at “wire speed”, many other solutions just don’t, i.e. Thunderbolt docks.
Compatibility: Targus Wins
TUDS plugs in via a cable and takes up zero deskspace. Other connection methods snap-in/on/hug/slide but all f them limit mechancial fuctionality of the docking device, i.e. https://targusblog.com/2014/12/09/its-got-a-kick-stand/
