When small and big HNI both have same allotment quantity, why one should apply in big hni?

Small HNI Category is between 2 to 10L and Big HNI Category is above Rs 10L IPO application. When oversubscribing, both the category will have 14 lots allotment. The only thing is small HNI will have lower allotment change because of higher subscription whereas Big HNI will have more chance of allotment of 14 lots due to lower subscription.
