If you are using it as the desktop, there is a large difference, it the slowest part of the process and a fast small file random read&write μSD does wonders.
I've used slow normal class 4s and then class10s, but moving to Samsung EVO/EVO+ * style cards.
or the now A1 rated cards has made a noticeable improvement.
It's most noticeable when you grab an old slow card and use it.
*these cards had the A1 rated speed range before A1 cards became a thing.
A1 specified a minimum rating they should be able to perform, so no matter which brand it is , it should be quicker than a normal card.
But for a bit of datalogging or similar then cheap Kingston cards are perfectly fine. Especially if just at the command line.
No idea for use as server e.g hass.io/openhab, or for TV streaming servers.
I guess they may respond a bit snappier to requests.
But look at the cost when it comes to that. 16/32GB A1 rated cards can be had very cheap.
For £2.84 I grabbed 16GB Kingston Class 10s form 'Amazon from Amazon' cards
Yet 128GB Transcend A1 are £15 at the moment.
SanDisk have been up and down, 32GB A1 being about £6 at the moment of which I also have plenty and the 64GB versions.
All Amazon from Amazon as it easy if there is a problem.
I just didn't need more then 16GB or the speed in my sensor devices, just sending via MQTT and a bit of local logging even few minutes, from Raspbian Lite.
