For Starter Kit, I think
these Plano boxes work well.
But I'm all in on Raaco for the rest of my ASL gear. Max flex, IMO, as you only need to bring the inserts you need for a game away from home. IOW, place all the relevant inserts into one Raaco Assorter and bring along with your system counters.
Another advantage of Raaco is that you can add (or subtract) new counters by adding or removing a single insert. I've found this feature increasingly useful as MMP has released new counters for various nationalities over the years. For example, adding the Eritreans to the Italian mix was a snap. More common have been new Assault Engineers (e.g., IJA 4-4-8s below), or special squads such as NKVD or Arrow Cross Militia.

If these new counters don't fit in a particular case, I can always use a smaller Assorter to store these new squad types. Ditto for vehicles such as Aerosans that get less use. Works great for Festung Budapest and Korean War (if you aren't able to dedicate an Assorter 55 just to the KW).

And another advantage of using Raaco (Assorter 55s) is that you can
lock four of them into a Racktainer, part of the Systainer system. I have five Racktainers and 20 Assorter 55s. Thay hold all of my MMP containers except certain CG-specific ones. What's more, each Racktainer can lock into another, and then into a small base on casters. A big investment up front. But IMO well worth it in the long run.
