What's better for personal cold wallet, single-sig + passphrase or 2-3 multisig?

Considering changing my setup, I thought about having coldcard + tapsigner + one key in a cloud in an encrypted file as a backup. Still kinda worry of possible scenarios I can loose 2 keys.
What do you consider better for regular stacking pleb? Or do you recommend some other setup?

I wouldn't bother with multisig if you don't need control among multiple people.

Now that's not true. Geo-disbursed multi-sig has the absolute best security triad tradeoff, you just don't need if you don't have a significant amount of money.
What's the security triad you ask?
Well, its the trade off between, availability, confidentiality, and integrity.

This is a good starting point: https://btcguide.github.io/

Whilst the signing devices on offer for multi-sig, and Sparrow as probably best-in-class bitcoin wallet, are all new since Michael Flaxman wrote (and recorded) this, the reasoning and comparatives of single sig v multi-sig are really useful to work through

There is not a solution that fits all the scenarios.
IMO, a hardware wallet with a passphrase is a good solution. Also you can have some SATs protected only with the seed and not the passphrase for a wrench attack scenario.
If the amount of SATs is big, maybe consider to have another device (different seeds) with the same set up.
Black up your seeds in metal and also in two different locations.

Definitely passphrase. That's what it's for.
No shame in using Casa or similar services (Blockstream Jade or Green has something)

2of2 multisig. Don't need to worry about the xpubs.
