They have excellent documentation, and their register-level APIs are relatively high level. Most of their chips fall into this or a related niche: good-enough computating and IO capabilities with RF for battery-powered devices. If I were to build something like this, they'd be my top choice. I wish they would move away from the third-party suppliers for making their integrated modules. So you could buy a 'nRF-53 module with antenna' instead of browsing third party websites. Speaking of competing with China: A Wi-Fi-capable Nordic chip is a glaring omission in their lineup. Give Espressif some competition!
