I don’t think a coin/token difference really matters, it’s what the product that it represents you should be looking into and what problem in the world it will be trying to solve. For instance, POA is trying to solve Ethereum’s scalability issues by connecting multiple side-chains together using smart contracts and and on-chain governance to make it more decentralized and not relying on a single person to make decisions.
POA is a great project to look into and will always be improving their work and the team is great, very smart, helpful and are not more interested in the money it may make them. They also have working products and main/test networks to be used unlike allot of Ethereum scalability projects out there as of now.
If you would like to know more about POA, you can search this forum and check out their wiki and Medium posts.

For more in depth information, you can read the whitepaper from POA. I promise it is not useless information describing bitcoin and decentralized networks like a majority out there.
