Overnight Hair Serum - Kerastase or Shu Uemura?

I already have repurchased the Kerastase 8H Overnight hair serum twice.

Has anyone tried both the Kerastase and the Shu Uemura? Do you prefer one over the other?

I love what Kerastase has done for my hair though the fragrance is way too strong for my liking. Wondering if Shu Uemura is superior?
