I own both, they're very similar in fit and in performance. The veil fits slightly tighter than the houdini (2017 version) and has an elastic hood, while the houdini has an elastic cord you can tighten. There's no significant difference in performance regarding being water resistent (they'll resist rain for about 15 minutes), wind resistence or breathability. For my usage (light to technical mountaineering), they're great pieces of my layering system that I almost never go without. If I needed to buy another, I'd buy the veil but only because of the significant price difference.
