I prefer butter, but I leave it in the fridge and if I want to spread something on my bread in a snap without thawing the butter, I use margarine instead. It's just another spread variant. I don't understand the margarine hate.
Unrelated to this, there's something weird going on on with the comment dates in this thread – or at least something I haven't noticed before. On some pages (for example, the top level thread) it says that your comment is an hour old, but if I click "reply", on that page it says 15 hours instead.
Just get the right kind.
My parents house has a pantry which is on the northern wall of the house and is ventilated, for most of the year the temperature in there is significantly lower than the rest of the house, butter and many cheeses do better in the pantry than the fridge. If there's a significant heatwave they need to be moved to the fridge.
By comparison, my apartment (constructed 150 years later) has an open plan with the kitchen almost in the middle of the floorplan. There's nowhere reasonable to store butter other than the fridge
