I've a single signature wallet but I heard recently that the multi-signature wallet has more security and that interests me as my stored assets increases.
It depends on how you set it up correctly, 2 out of 3 multisig wallets are fine if one is a hardware wallet, the other is in a safe place away from your home, and the third is in a safe place in your home. It's an extra layer of protection. If you can't manage a single-signature wallet, then managing a multi-signature wallet might be a bad option.
