For all my 9 loads I use CFE Pistol. The difference between the standard 5 grain charge and even a partial double load is immediately obvious.
My Lee progressive dispenses the exact same charge time after time, hundreds upon hundreds. Yes, I checked every ten, then 20, then every tray of 50 on my 10-10 beam. Never a variance. I still cannot help but look as I place the bullet.
Your bench; I like to keep things halfway organized and I find that plastic ammo boxes work for me. Since I have quite a few calibers I have some all blue, some blue and smoke, some smoke, some red some red and black, you get the picture. Midway's in-house brand are fine as are Berry's. I do not have bags of brass. When I am loading i also use the MTM Case Guard 150.
