ILNP Chai Latte vs Holo Taco Fifty Shades of Greige

How similar are these two? And which one has the better formula?

Ignoring the price of course. ILNP will ALWAYS have the better price point. But their international shipping cost is insane while HT ships international orders for free when you purchase $99+. Just finalizing my ILNP BF list before the big day(!!!) - I'm not getting HT polishes until december(?)
