“My wife and I run an insulation company together. If you ask us this question without context, I recommend cellulose, and she recommends fiberglass.
Either one is a fine choice. Here are a couple of things to consider:
Fiberglass tends to last longer (20ish years instead of 15), unless critters get into it.
Cellulose has a slightly better R value per inch; R38 is 11 inches of cellulose, but 13 inches of fiberglass.
Fiberglass is not as dusty as cellulose, although the dust settles out in 3 or 4 days after installation.
Rodents LOVE fiberglass, but they don’t like cellulose. If you’ve had rodent issues in the past, or you live in an area where mice or rats are common, definitely consider cellulose.
If you’re topping off your existing insulation rather than installing all new, it’s generally better to add more of what you already have.”
