I tested both. NVMe produced better benchmarks but make little difference to running most things. Programs start faster but do not run much faster afterwards as the limitations are network, the graphics chip, and the human brain to keyboard interface speed.
If you do use NVMe, switching the PCIe interface from 2 to 3 works in the short term. I have not tested long term heating or stability.
Measurements of long term write speed using big fast computers show many PCIe 4 SSDs drop down way past SATA speeds after just a few gigabytes of writes.
The result? I sometimes benefit from a fast NVMe SSD running with PCIe3 instead of PCIe2 which makes the upgrade worth the effort on my most frequently used Pi 5. The cost was limited by having a fast NVMe SSD left over from upgrading a computer.
There is not a useful difference with a cheap SSD. No difference reading email and browsing the Internet. There is no speed difference for most of my Pi projects. They run the same on a Pi 4 with USB 3 SSD.
