Looking to finalise RAM selection - Shortlist to 3 models

[CapitalFlight]

I need to choose my RAM for a i7 8700k build with a Gigabyte Aorus Z390 Pro Wifi motherboard.

I need help understanding if there's any differences or preferences of the below brands / models.
Prices are based on Australian market.

Corsair Vengeance LPX 3000mhz / C15 (CMK16GX4M2B3000C15) - $200
G-Skill Ripjaws V 3200mhz / C16 (F4-3200C16D-16GVKB) - $200
Corsair Dominator Platinum 3000mhz / C15 (CMD16GX4M2B3000C15) - $260

Each model is 2x8GB and they are all on the motherboards QVL list.

The Corsair Dominators would be Samsung B-Die if I manage to purchase the correct version (v4.23), however I'm not sure how I would go about that as retailers don't communicate this info.

So essentially what I'm asking is: 1. Is there a difference between Vengeance & Ripjaws, and 2. is the Dominator worth the extra $60?

There is no difference in performance between these three ram's & the dominator is not worth extra $60

Adding to @demon_king, if you found other brands with the same speed at lesser money, go for it. Also I don't know where you've been looking but I've just checked and amazon has them or equivalent at lower prices (Vengeance is nearly half the price)
