If you compare these both oracle tokens:

• Chainlink is the #1 but Band is growing. The latest contract with Fantom is quite promising 
• Band uses Cosmos blockchain whereas Link is on Ethereum network
• Cosmos DeFi projects represent a huge potential whereas Ethereum DeFi is suffering from high network fees
• Band is less expensive to use for the exchanges than Chainlink
• Band offers pretty good staking rewards

In summary, Link is still powerful, but Band will continue to grow since these both oracle tokens are needed, for Ethereum and Cosmos blockchain DeFi projects. Furthermore, Band has well decreased today and is rebounding on its support. It might be the last opportunity to buy it at this price.
