Popstar Ahri or Challanger Ahri

Popstar, because use with Arcade skin.

Both. is love is life

If already owned popstar, then popstar. If doesn't have both, challenger then wait for the next popstar sale.

For me tho it's Firefox all day every day.

Get both. I have both of Nami's skins from when I was maining her and plan to pick up the other two Soraka skins soon now that I'm maining her.

I like Popstar better, but I'm pretty sure challenger is limited availability, so you probably should pick that up now.

Popstar probably, it has a better thematic, but if you want a more "exclusive" skin take Challenger because it's going to be legacy (although I don't recommend to buy a skin for this reason).

I own Foxfire Ahri and Popstar Ahri, and to be honest... I really love them both! I mostly use Popstar Ahri cuz of the new sound effects, music notes particles, new model, new recall and new dance (she can also make the blue golem dance using her dance emote!)

I tested Challenger Ahri (Dauntless sounded better) >.< in PBE, I really like her splash, new model and particles! they are very dark evil kind of way (which is awesome). I played ahri using that skin for a couple times, and to be honest, her particles were too distracting, what I meant by that was... everytime I was about to cast a spell, I would focus on how the ability would actually look instead of looking at the enemy. That's not a problem though, maybe it's just me, it's something you have to get used to if you're using something so gorgeous. Moreover, it felt like there wasn't enough if you compare it to Popstar Ahri. Though I might end up buying it because it's going to be a legacy skin! I don't know yet, maybe no.

P.S. I bought Popstar Ahri when it was on sale! :) It was so worth it!

nether her original skin is best
