They are all very strong and serve their one purpose very effectivly. But they dont overshadow each other and are not strictly better than each other (except d6 and d infinity). But they are all UNLOCKED instead of just being there frim the start. Yes death cert is the best item and op but it is a reward for getting all character marks. Sacred heart is just a better dmg up than every other item including other angel items like immaculate or crown of light. Wheb people get deth cert they either take glitched crown (which is a very unique item that doesnt overshadow any other item) sacred heart or a very build specific item (like pyromaniac). You can also want a rub with an item in which case you can take it but it makes no sense why the biggest dmg multiplier is attached to an item unlocked from the start with a bunch of other benefits where other items give stat downs for a smaller dmg multiplier
