If you use ketchup quickly enough you don't need to refrigerate it.
Certain things taste better at room temperature ... cheese, certain wines, pickles and ketchup. Although, probably not together.
As for BRAND I was partial to Heinz, but I've had to stop using it because now they are putting high fructose corn syrup in it and it's waaaaay too sweet. There are a few "organic" brands that still use brown sugar or cane sugar but I haven't found one that I really like.
HFC ruined everything.
