Personally I am used to working on Polygon rather than on Solana and I can say that it is a really good network with fees less than one cent and transactions even with minimum fees don’t take more than one minute, so I am totally satisfied with it. But actually, we shouldn’t compare these two platforms, as Polygon is a layer 2 solution for Ethereum and Solana is an independent blockchain.
For those who are used to working with the Ethereum blockchain, Polygon becomes more acceptable. This is very convenient in many cases, since the wallet number in these blockchains is kept the same and they are both integrated into MetaMask. But at the moment, Polygon lacks hype and this can be seen in the Polygon ecosystem, which is significantly inferior to Solana.
