if vs else if method comparing

I wonder if there is any difference between those methods

public bool GetCondition(string s1, string s2)
{
    if (s1.StartsWith('a'))
    {
        return false;
    }
    if (s2.StartsWith('c'))
    {
        return false;
    }
    if (s1.StartsWith('b') && s2.StartsWith('d'))
    {
        return false;
    }
    return true;
}

and

public bool GetCondition(string s1, string s2)
{
    if (s1.StartsWith('a'))
    {
        return false;
    }
    else if (s2.StartsWith('c'))
    {
        return false;
    }
    else if (s1.StartsWith('b') && s2.StartsWith('d'))
    {
        return false;
    }
    return true;
}

Are they equal or is there a different behaviour to expect? If not, what is the better way to write?
