Extremely valuable. I’m about to publish my book on Ethics, and I have a chapter on Hedonism vs Eudiamonia. A key distinction I make is that happiness as defined by Aristotle is NOT a feeling or emotion.

I think it’s important to distinguish between Eudaimonia as a state that is grounded in objective criteria of virtue and excellence or what as a matter of fact is good for the agent, while hedonism is a subjective affective state, or what ‘feels’ good for the agent.

As you eloquently argue, Aristotle’’ concept of happiness is more about the quality and purpose of one's life as a whole, rather than transient emotional states.

Lastly, one of my guiding principles is that the proper place of our emotions are to:
1) Motivate us to do what’s objectively good.
2) Reward us for doing what’s objectively good.
