I haven't seen new data from celbrite in awhile, but I believe that grapheneos was the only truly secure phone from it for both bfu and afu as of a couple years ago.
Apple lost my confidence after they removed Advanced Device Encryption for British users (plus implemented age verification for them).

I think it's been said that nobody has yet cracked Apple's Lockdown Mode, but that's likely not truly comparable?
