I've already got my Samsung 980 Pro.
I am personally going for the Thermal Grizzly M.2 Cooler heatsink as it was readily available in Singapore. Just nice, I ordered it yesterday and it is thankfully here today. So I am all set to complete my PS5 storage upgrade.
As for the reason why I chose Thermal Grizzly, for PC usage, their thermal compounds are top notch and really lasts. As for EKWB's it all boils down to which can be delivered first. Sadly, it looks like the EKWB's M.2 heatsink has to be purchased overseas. And that's why I opted for the one that is readily available in Singapore and is actually proven to make great thermal products as well which is Thermal Grizzly's. So that's my recommendation to those who plan to get an M.2 cooler.
Purchased my Thermal Grizzly M.2 cooler heatsink off of Lazada from a local seller.
