climbing shoes

I'm truly needing new climbing shoes. I right now have a couple of Scarpa Vintage, size 11 (my "road size), and a couple of La Sportiva Nago, size 9.5. Shockingly the two of them fit, albeit obviously, the Vantage is significantly more agreeable.

I'm right now climbing around HS/VS, course/rock type subordinate.

What amount of distinction does type/model/make/"detail" of the shoe make to grades at my present level?

I'm speculating "very little assuming any".
