Yuzuha or Yi Xuan?

Given the roster below, who would you pull?

I'm playing my buddys account; raising it as my own. His acct is full F2P. I have both agents in my main, but its tough to decide how to balance out this alt acct. Currently at no guarantee, 50 pulls til 90, gotta win 50/50. I can no-life HZ grind to get the polys but that IS work.

My current roster (all M0):

Miyabi + Sig, YSG, Jane, Astra(Used Guarantee), Ellen, Haru, Zhao

Soukaku M6, Lycaon M2,

Pulchra, Pan M4, Manato M2, Billy M6,

Nicole M6, Piper M5, Grace M1,

Soldier 11, Seth M2, Lucy m5, Corin M6

And the rest of the A ranks.

Notable Engines:

Cauldron of Clarity

Hellfire gears x2

Steel Cushion

I'm tempted to build up pity for YX (maybe early pull), since Cauldron, Pulchra, and Pan are there but Yuzuha is definitely a flexible meta character.
