S2 and C2 are not old versions of S3 and C3 (C2 isn't even released yet), they are just cut down/lower cost version (but also with some added features for low power operation).

Uups. You are right. Although, in my defence the S2 was released prior to the S3.

Corrected it.

If it's a guide maybe you should mention that the original ESP32 is still for sale and still faster than some of the newer alternatives. There is also a new faster risc-v based variant without wifi/bt that was recently presented called ESP32-P4.

All current variants: https://www.espressif.com/en/products/socs

What use case does the ESP32 have?

Wouldn't it be better to just recommend the S3, where there is currently only one version available?

There are like a dozen different versions for the ESP32.

"Two or one CPU core(s) with adjustable clock frequency, ranging from 80 MHz to 240 MHz"

In this case it seems to be the better choice to just use the ESP-S3 with better encryption support and support for Cameras.

There are many different boards with ESP32 on them and lots of old projects that use it. The extra speed and features of the S3 is often not needed, so the cheaper ESP32 is a good option. And they both support cameras. https://docs.espressif.com/projects/esp-idf/en/stable/esp32s... https://github.com/espressif/esp32-camera

Some projects don't work with the newer boards (wled for example).

Partly this is because the Esp sdks aren't as mature for the newer boards. This is very true for the brand new C6 series, but somewhat true for th S3 and C3 lines as well

You don’t always need the fastest CPUs and the richest peripheral set. Those things are detrimental when you need to save power.

also s2 only has wifi

and H2 only has 802.15.4 (but also not released yet)
