I do find this type of comment puzzling. I've no objection to people not wanting to pay $30 for a piece of chalk, but to suggest it's no better than Masters is ridiculous IMO.
More grip. Fewer miscues. No need to chalk before every shot. It does what it says on the tin.
You can't state that unequivocally, going on a vague impression.
Things like this can and should be methodically tested.
It's hard to be objective when it's your $30 at stake.
You wouldn't have spent that much if you weren't predisposed to believe it works.
Testing and cold, hard statistics can produce a clear answer but nobody seems to have done this.
I believe that if you chalk properly, miscues are user error, every time.
The only question is, can a layer of chalk bail you out when you hit the CB where it shouldn't be struck.
For most miscues, the answer is no.
MAYBE there's a percentage of miscues that are right on the "miscue border",
that can be salvaged if you have the right flavor of chalk.
So what we're talking about is an event that might happen once a week,
and maybe only 10% or 20% of those rare events are affected by chalk brand.
You need
hundreds of miscues (which might take years over the course of normal play)
using both masters and kamui before you can make a rational, objective judgment,
and say "this brand of chalk definitely miscues less often".
