Solana is still better then polygon and solana have more advance features then polygon even ethereum contract. on the other hand polygon is like ethereum network and they haven’t much advance features. So i think solana must better then polygon network
I think the similarity that matic has compared with eth make matic somehow has the advantage, there is definitely a reason why many projects that migrated from eth choosing matic, there's big chance that it's due to the similarity of the ecosystem.
moreover these migrated coins didn't really need some additional features that solana offers, though it's true that both of them are such a good investment in the long term.
