I already have a cold wallet, but I'm looking for something more secure for long term storage. It needs to be usable by communicating the cold wallet with a phone alone (vs having to communicate with a computer), no personal node required, no DIY like seedsigner. Bitcoin only is fine with me.

I've seen Coldcard, BitBox02, Ellipal, Safepal, Keystone, Jade, but which one do you swear by and use for your HODLing?
