Micro SD, and MicroSD Express are two different standards. mSDe cards are typically backwards compatible with non-Express devices, but they operate at slower UHS-1 speeds. You'll get better performance with Micro-SD devices with a high quality A2 / UHS-2 card like a Samsung Pro series. (If the device supports A2 / UHS-2)
Express devices like the Switch 2 can only use mSDe cards like this one, and are not backwards compatible with MicroSD cards. The Switch 2 is the best known device to use mSDe cards, so usually the cards are marketed in some way for that. MicroSD Express is a PCI-E standard that supports speeds near 1000MB/s, while MicroSD typically tops out around 180MB/s.
The Switch 1 will be able to use this card, but is limited to UHS-1 speeds. (~100MB/s)
Why is this card specific for NS2? Is there any microsd storage size restriction on Nintendo switch 1 that makes it incompatible?
It should not be named microsd express since it is not a variant of current microsd with read write speed but also the bus interface like usb 1-3. Why don't they just call microSD 2?
Is this one the dopest brand or is sandick a better one?
Samsung is my #1 for long term reliability and speed.
Sandisk is #2. Sandisk, Samsung, Kioxia, SK Hynix and Micron make the majority of the NAND you'll find in tertiary brands like PNY, Lexar, Teamgroup, or Kingston. That's not saying the brands that repackage that NAND are bad, it's just that they don't have the name recognition.

That's a good question... The "Express" is because it's based upon the PCI Express standard, much like an NVMe drive stands for "Non Volatile Memory Express" because it too is based upon that standard.
The cards have both the legacy MicroSD interface, as well as the new PCIe standard, so they'll work with any modern SD card port, regardless of interface.
