In my opinion, Solana has more potential than Matic and it has also a different blockchain and crypto ecosystem. It is not a supportive blockchain from erc20 but a new program with a new ecosystem. Many of the new crypto projects and tokens are also launching on SOL blockchain and providing a big use-case of SOL in the crypto market. I prefer Solana and It is my own opinion.
That's right Solana is good, but there are still many obstacles. The frequent offline network on Solana makes investors panic, this problem has often happened on the Solana network, for my personal opinion for the long term of course I choose Polygon Matic for now because the supply of coins is limited and costs cheap transactions and also a fairly fast network.
