Personally, I think the two can coexist successfully an people visiting the both platforms have their distinct reasons for doing to. Op has definitely done a good job identifying both the advantages and disadvantages of the two which shows that they are both not perfect. Aside the abuse of KYCs and forceful implementation of this by the centralised exchange sites, I think I would be more tilted towards the centralised ones because they are easy to use without any need for understanding technical parts that surrounds private keys export, import, compromise etc.

People will only move exchange sites eventually that they are sure that their investment is secure and not about KYC which is the subject of dispute and the major difference between the two.
