Yes, it is. First, it is extremely customizable and Plano is not. Second, it achieves a FAR HIGHER density of counter volume than Planos do. With Planos, unless you install a whole bunch of additional dividers (and maybe even then), most of your Plano tray will consist of nothing but air. With RAACO, with its double-stacked small compartments, there is very little wasted space. I can fit an ENTIRE ASL counterset into one set of four RAACOs. In contrast, some people use virtual truckloads of Planos for their gear. Third, it is made of high quality material and can take a lot of punishment. Fourth, your gear will be eyed enviously by other ASLers.
Plane is customizable.
I can do a Bendis and have the entire US mix in one Plano with no dividers at all. Or I can do as many and have them in 2x 3701s dividers in place. Some nations require only one...eg Japanese, French, Finns.
Second, RACCO's trays make for tightly packed trays often requiring tweezers to remove counters, esp for those owners who over fill their trays and are also difficult for players with meat hooks for fingers. Plano allows a standard 26x MMC run to be easily gasped from one divider section.
Plano dividers are nothing more than Racco trays...in a different form.
With Racco double stacked trays you have to take out a tray to get at a layer of counters in the lower level, with Plano you don't have to do this. And this avoids attendant spill chances of a tray.
With Plano I can fit all ASL core modules (and RB, FB, KGP I/II, BRT, ABTF, PB, etc) in 19x 3701s and have enough money left over to drink quality beer. Racco owners have to resort to suck anti-freeze from their radiators...or bath tub gin...or worse drink...water!
I have never had a Plano fail to maintain its integrity...under any circumstance...mine are 15+ years old...and this is a young set, as I used to use sandwich baggies and stored my counters in the original ASL boxes.
My Plano is not the envy of any ASLer, but I don't care.
Select what system is best for your taste and style.
