What is the difference between Sakura57 and Kyoto206

[Sibon]

Fellow punters

I have not been to either Sakura57 or Kyoto206 but it seems they're both owned by the same people and have similar, if not the same, girls. Mostly Japanese.

I am asking experts here, what is the difference between them, if any. Does one have better beds or rooms or showers?
Do the girls swap around between them, or each shop has its own?

I notice from their websites that they are identical in prices and website design for that matter.

Many thanks in advance.

Sakura has softer mattress which allows for bouncy and spongy penetration as if you're on a spring.

Kyoto has harder mattress which allows hard pounding and precision drilling.
