POLYGON’S MATIC or Solana No Doubt, Both are smart contract platforms that support several DeFi and NFT protocols.
Polygon had a well-developed NFT ecosystem with many tools, marketplaces and other products being built on it.

IMO Polygon's closest competitor is the internet computer or NEAR, not Solana. Solana has broken a dozen times already and when discussing blockchains, the most important factor is security. The internet computer ICP runs on decentralized servers, not AWS like most other blockchains.
