What's really interesting going on right now is that adafruit/sparkfun have become radioshack, and aliexpress has become my go to place to find interesting new stuff.
I will say that whenever I'm doing a commercial project[2], however, I still use the more expensive adafruit/fry's/genuine arduino boards.
[1]: I help run a hackerspace in Phoenix, and I do all sorts of maker workshops all over the world, so having a bunch of weird dev boards and parts and stuff is pretty important to me. If those don't end up working, it was worth the $40 to find out.
[2]: Part of my life is helping create one-off experiential advertising installations. Usually these things have a stack of arduinos in them controlling lights, sensors, motors, etc.
It looks like the ESP32 is on the back. Sparkfun also sells an ESP32 that comes in that package: https://www.sparkfun.com/products/13907
