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.
Solana is a blockchain base-layer protocol, Solana can be considered as a direct competitor to Ethereum. The fact that the network went offline last year is very worrying and this is likely to continue if the transaction volume on the sol network increases rapidly, which will overload the sol network.
Matic and sol are both very good and worth using, but for investment and profit I think I will choose Matic for now because Matic is still undervalued compared to its potential.
