thinkpad x1 2-in-1 gen10 vs thinkpad x9 aura — which one’s actually worth it?

hey everyone, i’m deciding between two thinkpads:

1. lenovo thinkpad x1 2-in-1 gen10 (ultra 7 155u)  – 32 gb ddr5 ram / 1 tb nvme ssd  – 14" touchscreen convertible

2. lenovo thinkpad x9-15 aura edition (ultra 7 258v + intel arc 140v)  – 32 gb ram / 1 tb ssd  – 15.3" 120 hz oled display  – haptic touchpad

my use case: writing, research, ai-related work, creative stuff. portability matters, but i also care about a good display, battery life, and smooth trackpad experience. love bigger screens as well.

anyone tried either? which would you pick, and why?
