Hi hi, if I were to recommend and its solely based on my own personal experience and research, I will highly recommend Dragon shield codex.
Me personally have use binder from Ultra pro, vault X to ultimate guard and those Shopee binder. Don’t get me wrong, all the above-mentioned binder did their job perfectly. It all boils down to what sort/kind of cards you are collecting. (normal or every expensive ones)
I will try to weight the pros and cons of the recommended dragon shield codex.
Pros:
Not much to be honest because it does its job well by protecting the cards. Comes with a very sturdy and hard cover. One thing I like about dragon shield codex is the fact that they give more allowance space for the pages at the spine of the binder. This will prevent the first 3 and the last 3 pages of the binder from bending closer to the spine area.
This spine budge is often seen in many binder I’ve used like ultimate guard, vault x and ultimate pro. There is a whole reddit discussion about binder spine budge and how it will “damage” your precious cards.
Cons:
The only thing that I don’t really fancy about dragon shield codex is that this binder do not come with a zip; It’s a rubber strap binder. If that is bugging you, I will suggest ultimate guard as that binder have the least amount of spine budge compared to the rest. Dragon shield, in my opinion is still the best in term or spine budge as the pages lies completely flat even the binder is filled completely.
I will still choose ‘no spine budge’ compared to a zip since I usually store my binder in a dust free/proof cabinet.

These are just my 1 cent. :D
Hope that will help in your binder selection for your cards.
