That's not meant to discourage anybody from utilitarianism. There is no obviously better system. And we do need some basis on which to make decisions. I am just wary of utilitarianism for myself because I distrust its potentially confident-but-wrong conclusions.
I do think it's a very useful framework for elucidating the problems. Why is it we are willing to pull a lever to let the train kill one person, but unwilling to push a fat guy in front of it? I think that utilitarianism highlights the differences for exploring the moral intuition.
I have a poorly-elaborated notion that the moral intuition has some kind of universal, biological basis -- perhaps similar in origin to Chomsky's Universal Grammar. If that's true, we might be able to learn something from the neurobiology of moral decision-making. And that might in turn put utilitarianism on a firmer footing, or prove that no such footing is possible.
Just my $.02.
In the end, and perhaps in service of my original utilitarian impulses, I feel that entirely abandoning utilitarianism is the right path. This is sometimes referred to as `esoteric utilitarianism`, something that Sidgwick wrote about — suggesting that even teaching people about utilitarianism (himself being a utilitarian) might be immoral. Virtue ethics has been particularly appealing!
For example, some say it's more important to keep people's stock-invested retirement accounts solvent by increasing stock prices rather than take corporate profits and pay people who can't even afford groceries or rent, let alone invest in a retirement account.
Why is that obvious, why is that inevitable, and how is this inevitable communism utility-destroying?
Unless you are being facetious in your characterization.
