I've had 4 Kingston Cards that eventually quit on me within 1-3 years time.
I've had 3 Sandisk cards, 1 that has been lost, and two that are still working. I bought them in 2006.
I preferably use ADATA and AmazonBasics as they've been consistently 50%-80% faster write speed of other cards in the same class. Like how my Class 10 cards from Sandisk, Transcend, and Samsung transfer an average of 9-10 MB/s, AmazonBasics will do 15-16MB/s and ADATA 15-18 MB/s. My ADATA Class 6's transfer more files, quicker than Class 10 competitive brands with 11 MB/s
I own 20-something Micro SD cards of different brands and classes, and Kingston are not among that collection anymore. Definatel Sandisk > Kingston from personal experience, but personally ADATA is my goto brand.
If you want read and write speeds faster than ADTA cards have, then Sandisk's special high-speed cards are worth a look, but also twice the price. Supposedly the gold and red cards are as fast as some portable USB 3 harddrives.
