All SD cards are built to the same standard.
The standards organization is here:

Panasonic's parent company, Matsushita Electric Industrial Co., Ltd is the founder of the SD standards.
Panasonic brand would certainly be a good choice.
But I buy whatever brand is on-sale.
Never had a problem with any.
Rule number-1:
When you buy a new card, A L W A Y S format the card with the camera that it will be used with. If you fail to do this, you could end up with a card full of pictures that you can not access.
