What is the difference between OpenSea and SuperRare?

Could you elaborate on the key distinctions between OpenSea and SuperRare in the realm of cryptocurrency and digital art marketplaces? OpenSea, as I understand, is a decentralized platform that facilitates the buying and selling of a wide range of non-fungible tokens (NFTs), from digital collectibles to game items. However, SuperRare appears to be more specialized, catering specifically to digital art and creators, promising a curated experience. What sets these two platforms apart in terms of their target audience, functionality, and overall user experience? I'm curious to know how each caters to its niche within the NFT and digital art ecosystem.
