Thanks for your reply, this makes the most sense to me. The 2 options may be equal (maybe splitting the single sig is better because of less complexity), but they're both bad because of single points of failure. I'll take a look at the article as well.

Difference between 2/2 multi sig, and just splitting a 24 word seed phrase in 2?

2/2 Multisig is a terrible idea. Splitting up 24 words into two parts is also a terrible idea. With both cases you have TWO single points of failure. Just don't.

Also as others have noted Multisig is a difference in kind backup method requiring the xPubs of ALL keys in the quorum in order to reconstruct the wallet and spend the funds. Possibly one of the best setups we've come across so far is Stateless Multisig with something like SeedSigner or the [Blockstream Jade](https://www.athena-alpha.com/blockstream-jade-review/). 

We also have a full piece on [How To Protect Your Bitcoin Private Key](https://www.athena-alpha.com/how-to-protect-your-bitcoin-private-key/) that goes through a number of other common (but bad) ideas as well as best practices 👍🙂
