I am checking login of a user by this repository method,

  public bool getLoginStatus(string emailId, string password)
    {
        var query = from r in taxidb.Registrations
                    where (r.EmailId == emailId && r.Password==password)
                    select r;
        if (query.Count() != 0)
        {
            return true;
        }
        return false;
    }

I saw in one of the previous questions !query.Any() would be faster... Which should i use? Any suggestion....
