I can't pick one, if i do the time space continuum would summon a paradox FREEZING jesse perring and destroying the League of Legends therefore making 6 million players allergic to dust.
They are different.
Garen's spin continually hits the enemy as long as they are in it, also doesn't give movespeed boost (that's what his silence is for) and doesn't CC the enemy when they are hit.
Rammus's Powerball can only hit once, but it gives a movespeed boost and it slows the enemy when they are hit.
They are just... different.
You could have put more thought into this, like:
Two Annies with the exact same item build, runes, masteries combo each other at the exact same time.
