Proof is a strong word, but I will attempt to justify my commen(t).

I work as an instrumentation engineer for a multi billion pound company where I put systems together as for measuring and calculating flow, level, pressure and temperature. I have a first class honours degree in Electrical and Electronic engineering. As part of this, my thesis was on engine management.

I have built and mapped many engines in my spare time, on various aftermarket management systems. I also understand and can map - from scratch - certain modern OEM ECUs like Bosch Motronic which are several orders of magnitude more complicated than the most sophisticated aftermarket ECU.

I have no commercial interest in any system so my views are purely objective, based on experience and education.

It's my opinion that Megasquirt can't easily be beaten by other systems unless you have specific requirements such as fly by wire.
