I mean, butter is nice, but eating it by the stick? I scrape some onto bread, or cut off a small slice to fry something in, or maybe mix it into a cake.
It's worth it. Make sure you have everything you need, including tools, utensils, and dishes, before you start though. It comes together very fast and you will not have a spare second to go grab something.
Add a dash of cayenne if the recipe doesn't include it, otherwise I find the creaminess coats the palate too much and makes it taste too samey.
I recommend a butter keeper / butter pot to on the counter. They're designed to use water to seal the air out. Butter will keep for a week or two without any quality issues if you exchange the water in the butter pot daily.
Though these are an inverted system, so if your living space is consistently warm enough to melt the butter, it may not be a great solution.
'Murica, land of air conditioning (regular 90f+ weather).
I don't personally keep butter out like that as I do not own a toaster. Or a dining table. Or air conditioning to adequately handle hotter than 90f (cheap landlord at apartment complex plus upper floor apartment).
