When to use 1.75 mm vs 3 mm filament?

Why do we have two standard filament sizes, 1.75 mm and 3 mm? Does it really make a difference when printing? Or is the 1.75 mm just for smaller printers? In what situations should I be using 1.75 mm? When should I be using 3 mm?

Does filament have to be stored in an airtight environment?

For standard ABS and PLA filament, most distributors recommend storing the filament in an airtight bag. Does not doing this actually make print quality worse? I have left mine in the open for a year and have had no noticeable problems.

Advantages of PETG filament?

I was just shopping for filament, and saw some glowing claims about PETG being as easy to work with as PLA, but as strong as ABS, and less brittle. Anyone know if that's actually true, or what the tradeoffs are?
