It's a cost vs reward thing... so take this with a grain of skepticism, but, if durability was the sole consideration, nylon filament might give the most. nylon is very slippery so it's unlikely to abrade as fast. (this is why it's used in plastic gears.)
I think nylon does well with sliding friction, but have some concerns about whether it would hold up well to the kind of sharp edges you tend to have with abrasive media. That's from some observation on both commercial rock tumblers, industrial ball mills, and abrasive blasting equipment. I won't say I know enough from experience to say it will work for sure though.
that said, I suspect that depends on the kind of media used. sandy grit in a water solution or something would probably be fine.
Now that you mentioned it, I have a toddler and a cocktail shaker already. I'll slap some ducktape on the lid and hope to contain some disaster.
I suspect this comes with the benefit of burning off some of the kid's energy and entertaining the kid for HOURS
