If stored separately, I would consider the seed + passphrase comparable to a 2-of-2 multisig
My impression is that any multisig that requires all of its parts (x-of-x, rather than x-of-y) is inherently riskier because if you lose any key then you’re screwed.
2-of-3 multisig on the other hand would provide equivalent security from attackers with a reduction in personal-error-risk.

What abou Shamir backup keys?
I don’t really know enough about it to have an opinion, although most of the technical- and security-minded bitcoiners I’ve heard mention it suggest it’s not a great solution.
Couldn’t tell you why, though.
I really struggle to understand the difference of the risks between Shamir and 3-5 multisig. In my understanding it all boils down to having 3 private keys
