I've said it many times before, anything above 32GB behaves oddly (slower load and momentary freezes). And I don't have any problem using my fastest 32GB card (SanDisk Extreme Plus).
I've noticed no difference at all between the included 4 GB microSD with the 3DS and my 64 GB Sandisk Ultra.
Switch is not a 3DS?
3DS officially only supports SDHC
Switch officially supports SDXC
The hardware spec between SDHC and SDXC has not changed. The only difference is that SDXC only officially supports exFAT as the file system, which the 3DS cannot read. That's why an SDXC works in 3DS when you format it as FAT32. If there was any difference in the hardware spec, this would not be a workable solution.
