Multi-Sig backup question

[rogertb]

If I make a 2-of-3 (edit: or 3-of-3) multisig wallet and give the shares away, could I give two seeds to each recipient and still maintain the same security as a standard one seed wallet?

A: Seeds 1 & 2
B: Seeds 2 & 3
C: Seeds 3 & 1

Would there be any advantage to using one seed and one xpub key per recipient?

A: Seed 1 & xpub 2
B: Seed 2 & xpub 3
C: Seed 3 & xpub 1

Note: I don't want these to have watch-only access. This is strictly a backup.

if you want all participants to be able to spend, use a 1-of-3 wallet
