samsung seems to have the best performance/cost ratio. Wirecutter had a recent article with some suggestion - let me try to find the link

(the second article is micro-sd but you can get similar models as sd)

I mostly use sandisk because they seem reliable but are not the fastest (btw samsung ssd are >>> faster than sandisk ssd)-

One of the big issues is avoiding faulty clones that mostly don't work and have high failure rate. There was an article somewhere that show the rip off 'fake' packaging and it is pretty darn good with a few errors.
