Answer: The choice of which chain to use depends on your specific needs. If you need to move tokens quickly and easily between Ethereum and Stablecoins, then a bridge is the best option. If you need to move tokens between two different Ethereum networks (e.g. Mainnet and Testnet) then you can use a swap protocol. If you need to move tokens from one blockchain to another (e.g. Ethereum to Bitcoin) then you should use an atomic swap protocol. Ultimately, the best choice depends on your particular use case and the features you require.
