Just curious.
I've owned (M.2 PCI-E SSDs):
2x Samsung SM951 128GB AHCI PCI-E SSDs (very fast, MLC)
1x Intel 600p 256GB NVMe SSD (3D TLC, not the fastest, roughly similar to a SATA 850 EVO, I think, in most things. Had some "pauses".)
2x Adata SXG SU8000 128GB NVMe SSD (3D MLC, same controller as the Intel 600p, also lackluster performance. Have had some reliability issues too in my DeskMini.)
2x Plextor S8eG (?) 128GB NVMe SSD (TLC, don't think 3D, rather low write performance (*), have seen disk usage at 99% for long periods of time installing things. That was on a 3.80Ghz Ryzen 3 1200 rig with Windows 10.) These were only $75 shipped.
I really liked the SM951 drives, they had consistent performance (MLC), and great performance even at the smaller 128GB size, even though mine were the AHCI model.
Everything since then has been rather lack-luster as far as performance goes.
And the availability of the 600p is very spotty right now, in the smaller sizes. I though that they were discontinued, but was informed that there was just more OEM demand for them.
I think that the 600p should be the baseline for PCI-E NVMe performance. Anything slower is a waste of a PCI-E interface on the drive.
(*) Plextor M8Se(G) 128GB M.2 PCI-E NVMe SSD:
Second image is using 8GB test size, rather than 1GB, exposing the limits of the SLC cache, and going to the TLC NAND itself, I think.
