QNAP TS-453B vs INTEL NCU vs re-used gaming laptop

Hi,

I will be transitioning HASSIO from a RPI3B to another device soon.
I currently have a QNAP TS-453B. I could migrate to there. I also have an old unused gaming laptop (fairly powerful at its time, ~3 year outdated)
Otherwise, I could buy a dedicated Intel NCU.

What would the most stable, long-term, well-suited solution be?
