Only whirlpool gives forward/backward looking anonymity sets, which is a measure of how well hidden you are. Bitcoin is electronic cash and war on cash is already here.

Think of whirlpool as your own atm coin exchange cash machine where you never lose control of your own private keys but when you take cash/sats out from your own atm (whirlpool) how does one know which bills/coins/utxo that belonged to you. Choose a pool this is the only way to spend sats privately!
