I agree with all what was said plus I will add folowing :
That C152 plus the Nhadrian mod is realy great bang for your bucks.
For the default XPlane C172 there are also some mods which updates the cockpit panel to diferent setups to fit your likings. They are also compatible with Reality Expansion Pack so you will not compromise your experience.
For Pipers in XPlane I would recomend JustFligh’s offerings.
Talking Skyhawks / Skylanes / Pipers for P3D there is ultimate solution from A2A Simulations. Check them out, they are models which contains in base package Accu-Sim extensions which makes them top of the line products hands down… but also price is top oc ( still les than one flight hour in any of them )
