What M.2 SSD to buy?

[Cheki]

Building a new system but i'm unsure as to what storage I should get

▷ Samsung 970 EVO Plus 2TB M.2 2280 PCI-e 3.0 x… | OcUK (overclockers.co.uk)
▷ Crucial P2 2TB M.2 2280 PCI-e 3.0 NVMe Solid … | OcUK (overclockers.co.uk)

My two main options are these, is there much of a difference? apart from the speeds?

*EDIT* This will be used as a main (and probably) only storage device, with OS for gaming and storage for large video files etc

What is the usage? OS? If so, the 970 EVO Plus is much better than the P2 as it has better flash, better controller and it has a DRAM cache, while if the usage is storage or gaming they are more or less equal.

Thanks, I edited the post but it will be my only drive hopefully with OS and for daily stuff, gaming, etc
