Question RAM, Mixing different speeds vs latency

Hello, I have been looking to expand my PC's ram, my current kit is a Corsair Vengeance RGB Pro CMW16GX4M2D3000C16, which is a 3000MHz CAS16 memory, and the issue is that I've been looking for the exact same kit but I can't find it in stock anywhere where I live (Mexico), I can however very easily find 3200MHz CAS16 and 3000MHz CAS15 models of the very same brand and design, both for much lower prices than the exact model that I currently own (about a 30% difference in price).

The question is: Would it be better to mix my current memory with a faster one with the same latency, or one with the same speed but different latency?

Thank you all in advance.


Edit:
For easier reference,

My current memory kit:
CMW16GX4M2D3000C16

Options for expansion:
CMW16GX4M2C3200C16
-OR-
CMW16GX4M2C3000C15

Even if you found the exact same kit you have now it is not guaranteed that 2 separate kits will work together without issue. Then mixing kits of different specs increases the chance of issues. The safest option is sell your current RAM and buy a single matched kit. Take a look at the odd man out section here

So would you advise entirely against kit mixing or is there safer choice between the presented options?
