Against aliens I would use NN.
No matter how strong Stockfish is - it is open-source. Aliens can hire Houdart and make some minor improvements.
You need some obfuscation

NPS sort of does because LazySMP can keep widening the search. But as the search widens it also becomes less efficient
On 4C/8T CPU I checked 4 vs 8 threads. It takes exactly the same number of seconds to reach given depth, though 8 threads are faster and calculate more nodes

With Lazy SMP fixed depth is not a correct measure of strength. Probably the 8 threaded search is wider to the same depth compared to 4 threaded search, and probably stronger to the same depth.

how to run test tournament? I use Arena 3.5, cannot find how to assign different Threads count for participants.
Any other GUI or CLI-Cutechess?

I don't understand. Just set the UCI option in Arena or whatever to Threads=4 and 8. Play say 400 fast games at fixed time. It's also educative to do the match at fixed depth, with Lazy SMP more threads to fixed depth is usually stronger.

If you can't find the threads setting in the engine config, you probably have universal thread count enabled in Arena. (or whatever its called)
If you disable that setting you can set the thread count on individual engines.

Thread option in Arena is not per-engine, it is per-GUI.
Same is deep-fritz GUI (as far as I remember)

Arena definitely have this option universal to GUI, and it is not "disableable"
Please advise which GUI (or CLI-Cutechess options) use under Windows to run tournament with different Threads option for different engines.

This is not true. I configure different thread settings per engine in Arena all the time.
Just right-click the engine name in the engine output pane, click on "Configure <your engine name>", and set the threads setting to an appropriate value.
Arena does have the ability to set things like common hash table sizes and common books for UCI engines ("Engines"->"Manage..."->"UCI" tab), but at least in the version I have (3.0 build 2542), threads is not one of the common settings.
