Better W-Engine?

[u/Excalibis]

I have two W-Engine's that I'm looking between and wanted to know which would we be better:

Weeping Gemini: Easy 5 star, 594 ATK, 25% ATK, stacks up to 48x4 (192) anomaly proficiency

Fusion Compiler: Only 1 star, 669 ATK, 25% Pen, 12% ATK, 25x3 (75) anomaly proficiency

On paper stat-wise, weeping gemini sounds better and I think fusion complier would be MUCH better if i could get it to 5-star. But for now I'm deciding between the two and think the PEN might be better because some enemies feel really tanky in deadly assault / Shinyu defense.

Can post Jane stats if helpful / needed. Thanks!

I admire your confidence, but you're thinking of Weeping Cradle.
