What capacity are you using it in?
Hobbyist? Prototyping? Possible manufacturing?
I love the ESP product family and they're in a ton of cheap IoT goods.
I think if you're talking about hobbyist stuff, there's no reason not to start with an ESP32.
FreeRtos makes scaling your codebase a dream compared to the usual AVR stuff, they're powerful, they can be low-ish power, there's a peripheral for everything, and the IO Matrix is genius (no more worrying about having specific pins open for specific peripherals like I2C).
But for production, I don't think ESP is up to the standards of *NXP and TI when it comes to power consumption (although I might be behind on that with the new RISC parts)
I also don't think the Wifi stack on the ESP-32 is quite as mature, and if you use off the shelf libraries there are a ton of pitfalls when it comes to reliability
But the tooling is great, and there's a ton of activity surrounding them so for me none of those are deal breakers.
