Sigma 24mm 1.4 Art vs Samyang 24mm 1.4


I am about to buy one of this two lens but i cannot decide which one despite the tons of reviews i watched.
My camera is Canon EOS 80D. I want a wide angle lens to use for Astrophotography but i want the lens to be both APS-C and FF compatible. That's why i am between those 2 lens.

My thoughts and questions are:

Is the Sigma worth the extra 200€ for the Autofocus system? Is it that hard to achieve sharp photos with the full manual Samyang lens? Not just for Astrophotography but for general use.
Is the amount of coma the sigma produces high enough to be taken into consideration?
I know the Samyang is a master on that.
Do you know if any of this lens will have limited performance on my Canon 80D?

Do you have any other len recommendations?

Thank you
