What is the difference from others?
Walton, Vechain and Wabi are all aimed at helping people to track goods or services, interconnecting things (IoT) or avoiding scams.
Walton is the biggest among them because it has numerous approved patents, Rfid technology and IoT automation, still little appreciated by the market for its enormous potential; collaborations and agreements already active with Icon and Aion; launch of masternode and cpu mining;
VeChain, the one with the largest capitalization, you can see it similar to Neo: you have a platform for Ico, a proprietary blockchain shortly, generates Thor in proportion to the Ven possessed (as Gas for Neo), more active in the field of medical solution, luxury and fashion; masternode arriving in June.
Wabi is the smallest of the three, with a capitalization of only $ 30 million, and is aimed at the huge Asian market, China in particular, offering an optimal solution for counterfeits and frauds; it allows you to see the traceability and security of each product, through a real app already present in the market .... constant growth, weekly updates and continuous agreements with numerous companies; masternode coming soon.

If you want to invest in security I recommend Walton and VeChain, but if you want to have a greater return, with a slightly higher risk, then I definitely suggest you Wabi because still little known, and with a market value of only $ 30 million potential return can be explosive!
