If they are functionally the same, I don't care. I've never had a TTGO board arrive DOA, but I have one where the UART chip died after a bit. But at $5 each, it's a risk I am willing to take. I noticed that the last batch I bought had a blink program already loaded.
I have a couple of ESP32 boards, but never needed them when a D1 Mini would do the job.
