The F/A-18 included in MSFS is an E model, not an F. The E model is a single seat and the F model is two seats; pilot and WSO. For that reason alone, using AI assists would be unrealistic.
As far as the flying characteristics go, it’s a little touchy in the roll axis but I can probably dial that out with a sensitivity adjustment. No stalls, no uncommanded rolls. Don’t forget the you’re the pilot. Fly the jet. This isn’t a passenger plane. Make it do what you want it to do.
