Fwiw, I use both. I really like both. I said c3 leads was my own experience following this community.

As it was explained RISC v has better support because it's open and can be emulated with qemi/llvm/wasm whereas xtensa cannot. Espressif has tried to address this as a licensee, but they don't own xtensa is owned by Tensilica Inc which is owned by cadence.

Cadence has not allowed details of the JTAG to be published. Because details of xtensa aren't open source licensed. This makes things such as the openocd debugger, probe rs etc aren't as good, and this situation is unlikely to change.

Debuggers are nice.

I'm working on the esp32 c3 embassy-rs support this weekend. I personally prefer the RISCv because I think it is easier to emulate and not need to flash a physical device , this means Dev work can move faster with better tests.

Just my opinion.
