Which is better to use batt insulation in a wall vs. blowing insulation in?

I have 2 exterior walls, 1 wall plaster is removed and when closing back up the walls I'll be installing batt.

On the 2nd wall, the plaster is still up and I'm debating adding a day to my project to rip it out and install batt on that wall too.

Thoughts?

Thanks!

Dense-packed, either cellulose or fiberglass, is far better. Figerglass batts are the worst insulation made, unless perfectly installed (a rarity) and then it is still not great. It's OK, tho.

Will you be caulking the stud/sheathing/plates joints before insulating?

Will you be air-sealing the drywall (ADA-- airtight drywall approach)?

Do you have any rigid foam board on the exterior?

Where are you located?
