The most famous wallet for Ethereum is MyEtherWallet.
I already forgot the whole story, but then the development team split up and another wallet appeared - MyCrypto.
Their functionality and interfaces were similar because they were developed by the same team.
I prefer MyCrypto, it is more user-friendly and I like its interface better.
But Ethereum wallets are compatible with all applications and you can easily use the wallet created in MyCrypto in any other application.
Previously I only used MEW to store and make Ethereum transaction. I haven't tried the "MyCrypto" wallet because I don't need it so far. Maybe try it next time for some experience. While using MEW, I think we have had good experience managing our crypto asset based on Ethereum and to date MEW is still believed to be one of the best Ethereum wallet to date. I hope the OP can choice one of the recommended wallet. This should be based on need and a good level of security.
