I prefer the NVMe base boards rather than the hats to keep the top side
clear for fans and GPIO cards.

I've got the Pimoroni NVNe base on one (with the pibow coupe 5 case and
official cooler - make sure you get the long PCie cable), the other is
in the Argon NVMe case (from PiHat) which has an NVMe base board and
cooler built in. The performance of both boards is identical with the
same drive.

Note that the performance of NVMe drives can vary considerably though.

I had no problems with either of mine recognising the NVMe. I was using
USB SSDs with each of them, so I booted from a temporary SD card, cloned
the SSD on to the NVMe, and then rebooted with just the NVMe present.
