What is the difference between OpenSea and LooksRare?

Could you elaborate on the key differences between OpenSea and LooksRare in the world of non-fungible tokens (NFTs)? Both platforms seem to cater to a similar audience interested in digital collectibles, but I'm curious about how they diverge in terms of user experience, transaction fees, available collections, and any other distinguishing factors that might sway the decision of an NFT enthusiast. Understanding these nuances could help collectors and investors make more informed choices when navigating these rapidly evolving marketplaces.
