Do you manage excess inventory by item count or stack size?

I have a recycling setup that processes anything over 20k in logistics. It's a passive way to generate increased quality. This usually means plates and such.

The other day, I changed one to do anything over 100 stacks. Basically more than 2 chests full. (chest holds 48 stacks) the line started chewing thru all sorts of weird overstocked stuff like recyclers and foundries. It's kind of hilarious how many stacks of recyclers I was stocking up. (side note, why do artillery shells stack to 1 but an entire building stacks to 10? I know it's balance but it strains plausibility.)

I'm still undecided how I should manage my inventory. How do you manage yours? Stack or count?
