I did a subdividing experiment on an old school counter tray that I use. Worked out pretty good. Cut pieces from another defective tray with an exacto and superglued them into this tray.

The law of diminishing returns kind of informs how I store my own stuff. For example, you have separate bins for example for First Fire AAMG and First Fire BMG, which you had to make with scissors and superglue.
My thought is - if you mixed both these counter types into an unaltered bin - you have a 50% chance of pulling the one you need sight unseen, and by the time you look at three counters you're pretty much guaranteed to have the one you want. Even with all six categories mixed together, it's a 20% chance you'll find the one you want on the first try.
On the other hand, with the additional subdivisions during clean up (unless you're really diligent during play) it's going to take a little longer to figure out the identity of each counter pulled, and remembering which bin is which. If you have all six types mixed together, you can just pitch them in based on their colour and not even have to read the text.
To each his own, but for me, I've found having a lot of subdivisions provides no real advantage.
