Answer 1

I vote that it does not matter. Pick what makes the most sense for your application. Use human readable values. Pick nice names for variables and columns. Only in really extreme cases will you need to tune. When you find out that you need to tune, tune. Until then, go with whatever makes the most sense from a business or human perspective.
