Whirpool you mean Samourai?
Yes. Samourai is the name of the team/wallet behind the Whirlpool implementation of coinjoin. Whirlpool is also accessible via Sparrow, with other wallets in the works I believe.
My previous experience means I won't use Sparrow but I'm looking at Joinmarket.
I'm 99% certain the link you have included there is a scam site. I've never heard of it before despite using JoinMarket for years, there is no mention of that site whatsoever on the JoinMarket github, and the download link directs to a .exe file which does not exist on the github releases (
https://github.com/JoinMarket-Org/joinmarket-clientserver/releases).
You should only download JoinMarket from the releases link I have given above and verify the download with the provided PGP signatures before installation. I'm pretty sure that .exe file will be malware.
