Are digital controllers the same?

[MMMMSMOKE]

I have been looking into A-LOT of controllers and they all have the same duties - auger, fire, fan, power and under hood temp. It seems they all even have the same connectors. The only difference I see is wire color.
At the risk of loosing $60, rather than asking the forum, is there any obvious or scientific reason I couldn't put a Treager digital controller in my ZGrill pellet smoker?

My ? is if both are none PID controllers is why would you as that's not a upgrade imo, I would bite the bullet if you are determined to change it out and put a PID in
