He argues that passphrases are flawed due to their 2-2 setup, posing a risk of losing funds if one part is lost. Nevertheless, the same vulnerability exists for SeedXOR (2-2, 3-3, …). I don’t see any downside as long as the passphrase has a 256 bit entropy. Multiple backups are essential for both solutions. 

Lopp on Passphrase backup:
„This gives you a security model that's the same as a 2 of 2 multisig setup. Do you know why 2 of 2 multisig isn't popular? Because it has 2 single points of failure - if you lose either part, you're screwed. I've seen quite a few people over the years get locked out of their funds because they forgot or lost the passphrase that accompanied their seed phrase.“

Lopp on SeedXOR backup:
„Seed XOR is, in my opinion, a superior way to achieve the properties that folks try to get with a "25th word passphrase" or via naive seed splitting, while decreasing the complexity and improving plausible deniability. Note that this is essentially an N of N (2-of-2 / 3-of-3 / etc) split backup, so you're going to want multiple sets of XOR'd backups to ensure that losing a single plate doesn't cause catastrophic loss.“
