I agree. This article seemed like person who wanted to pick something up and make something and just have it work. The ESP is often a good series for that. It is widely used and well tested. Cubecell is great for very low power. But it took more work to get it working. The scale of use is clearly lower so I ran into bugs at the time that I'm sure are worked out by now. The result was great mind you. I built a remote controller for some things and it will easily last 10 years on a simple 1/2 as cell. nrf is definitely more featured and thoroughly tested then either. But the startup can be harder to do depending on what you do (ie running zephyr on it)
