I honestly think HP vs Def is preference... if the boss wants to kill you with a nuke, then damage cut (on future devil accessories) will be superior to both.
And while true on 100%, dbl is still supposedly checked before trpl so the more dbl you have, the less trpl should activate. Which will soon be easier to do given tiara set effect... forgot where I seen it, but awakened kami supposedly have a base double of at least 10%, so tiara set pushes that to 25%. And some kami like Titania can push this a lot higher. And you can even toss in union buff for those events for up to 25% more making it a base 50%. Doesn't need to be 100% for that to be an issue.
Yes and no. 4% HP and 4% DEF on accessories both increase effective HP by 4% when no other source of stat in question is present. So if you have 100% increase in HP from weapon grid, 4% HP from acc becomes 2% effective HP increase. Same with DEF, if you have 100% increase in DEF, 4% from acc becomes 2% increase in effective HP.
Now then, do you have 100% DEF increase ?
But wait, there's more. DEF increase not only effective HP, but healing power too. Let's make such an example.
10k base HP, some kind of 2k heal, mob hits for 4k.
With 100% HP increase: Kamihime health pool equals 20k, she gets hit for 4k and healed for 2k. That leaves us with 18k HP.
With 100% DEF increase: Kamihime health pool equals 10k, she gets hit for 2k (4k * 1/(1+1) = 2k) and healed for 2k. That leaves us with 10k (full) HP.
So DEF is better in almost all cases than HP.
It's most probably not and tbh I am not sure where people got this idea of "double is rolled first". From my short tests I suppose that values above 100% are scaled to 100%. So for example if you have 200% double attack chance and 200% triple attack chance, it will result in effective 50% chance for double attack and 50% chance for triple attack. Does that mean that double above 100% chance for combo reduces chance for triple ? Yes, but it doesn't mean 2% increase in double will reduce triple by 2%.
Now, if anybody is interested why scaling. It's probably because devs were lazy and it was easier to make guaranteed combo attack buffs. You can just slap 200% double attack increase and 50% triple attack to get the guaranteed combo attack with probability of 80% DA and 20% TA (not exactly, but lets say it's close enough).
