Should I use more useMemo to instead of React.memo?

[filefoxper]

I want to know which I should use more. like:

const Parent=()=>{
    const myElement=useMemo(()=><MyComponent {...props}/>,[...props]);
    return (<div>{myElement}</div>);
}

compare with

const MyComponent=memo(()=>...);

const Parent=()=>{
    return (<div><MyComponent {...props}/></div>);
}
