Mechanically simpler or not, I finished a Garmin install last week on a piston-engine Lancair. I would absolutely call the avionics and engine indicating systems intuitive and easy to use, even without being a pilot.
While it's no G1000 or G3000, the G500 TXi, GTN 750 Xi, and GI 275 are all very straightforward, with engine indications being displayed on the G500 Xi in an easy to navigate package.
