Crucial P5 Plus or WD_Black SN850X for gaming?

[CK61938]

I am in the process of purchasing the parts for my gaming PC. Here's what I have so far:

CPU: AMD Ryzen 7 7800X3D (upgrading from Intel Core i7 5820K)
Mobo: ASUS TUF Gaming B650-PLUS (upgrading from MSI X99A SLI-PLUS
SSD for OS: Crucial P5 Plus 500GB NVMe (upgrading from Western Digital 500GB M.2 SATA)

What I plan to get:

RAM: Corsair Vengeance RGB Black 32GB 6000MHz DDR5 Memory Kit
AIO Cooler: Kolink Umbra VOID 240mm AIO

What I will be keeping:

GPU: ASRock Phantom Gaming RX 6900XT
Case: Lian-Li O11D-Mini
PSU: Corsair SF750

In addition to this, I want to upgrade the SATA SSDs I have currently have (both are Crucial 1TB) to 2TB NVMe's. However, I am not sure which is best to get for gaming purposes. I have read it's a bit of a tie between Crucial's P5 Plus or WD_Black's SN850X. Both are bit pricey (in my eyes anyway). But I would like some more advice on them, please. I am also looking at the SN770 from WD_Black.

In conjunction to this, would I be better off getting gen3 PCIE NVMe's instead of gen4? Would that make any difference to gaming loading times and what not? If you are asking what games will I be playing, it's a mixed bag:

Call of Duty MW II
Football Manager 2023
DC Universe Online
Spider-Man (both the OG and Miles Morales)

And of course, I am preparing for Starfield (which reminds me, I need to contact OcUK about getting the game with my new CPU).

Thanks in advance!

Thanks so far your advices, guys.

The P5 Plus 500GB drive arrived today, which will be for the OS. I will consider what you have suggested, but if the games don't need anything too punchy, then I should be fine with whatever I decide. Whether it's SN770 or even a P3 Plus.

I still wouldn't buy a QLC drive, even for a games drive, unless the discount was very large. E.g. rated endurance of SN770 (2TB, TLC): 1200 TB written, P3 Plus (2TB, QLC): 440 TB written

SN570 would be my choice for a cheap drive (2TB, TLC): 900 TB written.

Ok, noted. The SN570 does look like a good deal. You may have made my decision for me.
