Another point that doesn't get mentioned here (because it isn't about the cryptography) is that 'Ecash tokens are bearer asset tokens. This means the data that gets stored in the wallet represents the actual money itself. Should the storage be wiped, funds will be lost.'
With Monero your funds are safe as long as you have the seedphrase somewhere.
'the mint will almost certainly be able to identify a receiver that is getting paid through the mint.'
With Monero the receiver can't be linked to an address or any funds moved on the blockchain.
'Larger amounts most likely have less good privacy properties, due to their token denominations being rare. Cashu uses fixed (power-of-2) token denominations to create a hide-in-the-crowd effect. But the larger a token gets, the more likely it is that fewer and fewer of them exists, and at some point there is no crowd to hide anymore. If there is only one token of a specific denomination, it can always be linked back to its creation.'
Monero hides all amounts.
'Cashu does offer decent privacy at the protocol level, but it does not take into consideration network level privacy. mints may try to collect network data such as access time, IP addresses and or other metadata.'
That is a similar problem with Monero. Though it can either circumvented by using your own node or using a VPN/Tor/I2P with a public node.
BTW it's not recommended to use Tor + a VPN

'Cashu transactions happen 'out-of-band', which shifts the responsibility to use secure channels for sending tokens. The most secure channel is to send tokens air-gapped (via QR codes), since it doesn't leave any trace of out-of-band data. If tokens need to be sent over a network, it should always be done over an end-to-end encrypted channel, preferably with self-destructing messages.'
So most everyday users will just send it through unsafe channels probably. With Monero even non-techy users profit from nearly all of the privacy features as TX gets handled/send by nodes.
