Why is Ethical Egoism so out of favour?

What makes something like Utilitarianism so much more popular among philosophers than Ethical Egoism? I have read the SEP article on Egoism and it has not brought me any closer to understanding why it is supposedly so inferior to other moral philosophies. It mentions a lot of different arguments that have been levied against Egoism but also provides seemingly sound counterarguments. All while ignoring the similar arguments that can be brought against Utilitarianism. Understandably that isn't really in the scope of the article but it doesn't help me with my question.

Ethical egoism certainly seems internally consistent to me so am I missing something? Or is it simply the case that Ethical Egoism does not fit the bounds for what a moral theory must be? If that's the case then where does it fail?

Because the idea that it is moral to only help yourself is arbitrary and totally random. It doesn't really make very much sense to begin with. It conflates personal benefit with the idea of an objective good to do. Even though those don't have much reason to be conflated, and are often seen as opposed.
