So… I’ve been deep in research mode on zkSync and Polygon technology.
After reading wading through a lot of information, I’ve come to the conclusion that I like both technologies a lot. However, zkSync is probably the superior choice for security of tokens.
Polygon’s main problem with token security is the Bridge between Ethereum and Polygon. If the Bridge is compromised or dismantled - intentional or not - no tokens can transit between blockchains.
zkSync operates mostly off-chain. So, most of zkSync’s functionality is entirely subject to centralized operators. However, the deposited tokens never leave Ethereum mainnet. They are all held in this contract address and can be retrieved by the original depositor or whomever is the current owner according to Ethereum mainnet states. This remains true even if the entirety of the zkSync platform is taken down for whatever reason.
However, retrieval of tokens directly from the zkSync smart contract is non-trivial. To do so, one would probably need to manually write a contract on Etherscan… but, the tokens can never be lost or stolen by zkSync.
One of my main purposes for exploring Polygon is the already existing DeFi platforms.
However…
It seems the zkSync is near the release point of a zkSync swap platform.
I attempted to connect to it, but was presented with a “Wrong Network” error and a Metamask prompt to switch to a Ethereum testnet.
This is very exciting for me!
I’ve now elected to deposit my earnings into zkSync. It looks like the zkSync will evolve rapidly enough to support my FOMO personality… which hardly ever works out well… but is fun nonetheless 
Therefore, while I like Polygon… I’m going to withdraw my previously expressed desire for SNO payments via Polygon for the moment. The increased assurance of token security is worth the wait for increased platform functionality.
Test ETH needs to be obtained from the testnet faucet in order to use the test zkSync swap platform. In order to obtain Test ETH from the faucet, one must place a post on Twitter. Since I don’t use Twitter, at all - ever - never - not if my life depended on it… I am unable to test the Swap Platform.
But… I might make an exception for the possible future of some type of reward for being an early adopter/tester of the platform. I have to think about that one… maybe a throw away account/blockchain address or something.
