Thank you
Naturalwetstones gave the answer, Yae Botan is more abrasive than Botan
here is the ful progression

Yae Botan may be more abrasive than regular Botan.
But Yae might also not be more abrasive. Evaluate each piece on it's own merits.
Geologically, Yae B is a different layer Botan. Still, it shares the moniker, and it's known for producing stone, similar to Botan, but less consistent and often more abrasive. There is more sand next to the YB seam but Botan is not immune from that sand issue. It is very possible to have a piece of Yae that is less coarse than a piece of regular Botan.

Then there is speed to consider... a harder abrasive that is finer might be faster but not coarser. A less consistent Nagura, Mushi, for example, isn't so much 'just coarser' as it is less refined and usually in-consistent.
In a general sense, the Nagura can be viewed in a simplified coarse-to-fine graph but the real picture is much deeper than that.

Helping to confuse the storyline, there is a ton of fake Yae on the market. Not even sure it's even Botan.

What @Gamma said, I’ll add that from my experience true Botan is a lot more pasty than Yae and faster.

Usually, yes. Almost always actually.
There is a very grainy Botan that is definitely not Yae but is still grainy. Has a reddish/orange hue. But there are red/orange Botan that aren't grainy too.
I bet someone will copy that and put it on their website tomorrow.

Any recommendation where can I get a true and good Botan?
