p7*s, or Platinum Units, have higher stats (ATK and HP) than most 7*s that are available at the moment, and cannot evolve (so you only need to pull/exchange for them once to get the most out of them, unlike other units that you need multiple copies to evolve together to create a +2 or +4 unit).

Platinum units also have a Unique, which so far has been different for each Platinum 7*. This gives each one a niche that's useful in different situations/events, and not one Platinum 7* is defined as "the best" (though some, such as Jeanne d'Arc, can easily be argued to be a great choice because of her wide range of utility).

When attacking with a Platinum unit, they also have "X" added to the end of the command (besides the combo-startup commands such as Flurry, Slice, and Pound), which are "Flail X", "Upper X", "Dice X", "Smash X", "Beatdown X" and "Blast X". Platinum Flurry units hit 4 times in their normal Dice X (without a Rush or Multi/Rush skill activation) compared to the 3 times of normal Flurry units. You can also only have one copy of a Platinum unit in your deck at a time (So you can't have two Baldrs in your defense deck, but having a Baldr, a Nina (Swimsuit), and a Daji would work)

Platinum 7*s are usually released in the medal exchange a week after the packs they were in become unavailable, with CtA p7*s (Daji, Elisabeth, Jeanne d'Arc) taking a longer time to be made available in the medal exchange. Each cost 4 platinum medals to redeem. Selling a Platinum unit will give you platinum medals instead of normal medals that can be exchanged for items like AP/BP, Grimoires, and Spirit Gems. A Maxed-loyalty (1000 loyalty points) Platinum unit can be sold for 2 Platinum Medals, and platinum medals can be obtained from some event rewards and were one time in a Pack as a bonus item.
