which fabric would you choose for a chore coat, indigo sashiko or olive wool?

I know this is purely subjective, but I might as well ask since I can’t decide. I already have a medium wash Levi’s sherpa trucker, and a black Carhartt WIP Michigan chore coat (that’s like denim or canvas?), so I’m leaning towards the wool, but the sashiko fabric looks really unique too.

Thoughts? And thanks in advance!
