It's about Lexar NM610 500GB and Samsung 860 EVO 500GB.
I'm a gamer (multi ran games at same time) and a home user with around 18 hours of mixed content usage. Really I can't choose between these to. I must mention that I don't have 4K VGA or monitor (for now) so that part is not my matter. Only speed and cost is the main matter (Brand is not a matter for me too).
I saw many reviews that I saw Dram-less NVMe is much better than Dram SATA SSD (in thanks to HMB tech as a Windows 10 user).
If you are and NVMe Dram-less user or you have any experience regards my matter please share it with me.

Thanks

NVMe drives are not as reliant on DRAM because the protocol itself is superior to AHCI. For consumer use, you don't need DRAM with NVMe drives. The WD SN550, for example, is excellent without it. To some extent, a SATA SSD with DRAM can in some cases be faster, you need to look at the overall design of the drives as well as your specific use case to make a proper determination. A drive like the NM610 (SM2263XT) can fall back to host memory buffer (HMB) by using a bit of system RAM, too, which reduces scenarios where you'd be having cache misses.
