#188 looks better to me.
Donīt forget, with the higher slant the whole trouser gets pivoted around the lower hip side seam/ waist. so the crotch/seat seam is pivoted as well. Removing the slant means altering the position of the seat seam.
I recommend to mark the lower belt edge to the trouser with a sharpend chalk. This will give you hints for the waist seam run.
