ESP32 - which board ?

[picandmix]

Hi,

Was looking at the ESP32 boards , seems there are a couple of variants available locally using  the WROOM based ESP32 38 pin DevKitC  and the 30 pin DoIt

Apart from the extra I/O pins are there any major differences between the two ?

Though these boards are dearer they are next day delivery, but apart from the lower cost is there any reasons/ key differences to look at some of the similar ESP32 boards from the far east ?
