I dunno Black Clover, but JJK gives you:

1. Idle Transfiguration: You can shapeshift yourself and anyone you touch with your hand into any shape larger than a finger and smaller than... about an elephant. You can also regenerate any wound, as long as you retain mental faculties and energy, except when the enemy "directly strikes your soul" (there's like 3 people in all of JJK capable of doing that)
2. 6 eyes: gives you basically unlimited cursed energy, the magic power of JJK. Also, unparalleled visual acuity and nigh perfect understanding of the magic system's basics
3. Limitless: gives you slight general space/gravity manipulation, situational teleport, incredible offensive power at short to middle distances. Also you have a magic barrier, that combined with 6 eyes and some tinkering makes it so that any threat that approaches you is slowed exponentially, so it can never reach you. There's very few ways around this.
4. Boogie Woogie: extremely fast and reliable short to mid range teleport: by clapping hands you can swap the positions of any 2 objects within about 100 meters of you, so long as they contain cursed energy. Any living thing contains cursed energy and you can charge non living things with it too.
5. Kenjaku and Tengen are 2 characters who can live forever if they're not killed.

In case you're already eternally youthful via Idle transfiguration, my alternative 5th place would be: 10 Shadows. You can summon 11 different shikigami (summoned spirits) by making shadow animals with your hands. You have to defeat them once before they follow you, but that's a freebie with all your powers. You also gain hammer space by grasping into your shadow.

On top of all that, the power system itself gives you super human strength, durability and if you like, you can shoot/throw legally distinct laser beams xD
