I like the ease of setting up a non custodial multi-signature set up (personally used with 3 Tapsigners from CoinKite). With on-chain fees currently where they are, it may be a bit expensive to set this up, however you can monitor when fees drop lower and secure your savings. I choose non-custodial set up of Nunchuk over Unchained's Caravan vault (which I have also tested and is solid as well)
