Comparing Zephyr and TNEO is like comparing apples and oranges. Zephyr is full fledged operating system with networking etc while TNEO is more like basic building blocks of os for those who want to implement everything themselves. I can warmly recommend Zephyr for BLE usage. It is up to date with recent bt specs and implementation is really solid.
