It is not possible to compare these arcade F-16 and arcade Tomcat and whatever other jets with no functional systems at all and fantasy cockpit button layout are with absolute phantastic top-notch DCS jets.
Study level in Flight Sim 20 are only PMDG (and very likely of course Fenix too) - but not these available arcade jets. Forget these - they barely resemble a real F-16 and Tomcats etc…
Go for the good quality study-level airplanes only: PMDG Fenix Carenado and some others.
