Since it's been about 20 years since my last responce here...
BlueChip TP35 and TP40, rounded triangle flatpicks, and BlueChip JD thumbpicks. I reshape the tips of the thumbpicks to suit because they're both too long and too pointed when new. Neither pick seems to wear...ever.
I got on to the brand when Uwe Kruger handed me his Henderson flattop guitar to try. I wasn't all that thrilled with the guitar but his pick was awesome. I immediately ordered two flatpicks, then two more, then the thumbpicks. Must be 15 years or so now and I neither lost not worn them out.
I rarely use anything else, though when I do it'll be nylon Jim Dunlops, Ultex, or Wegen.
