Except for paragliding - you won't find any other form of civilian flying more challenging nor rewarding.
Flown big jets for excellent companies, instructed class A tail draggers and gliders; also flown helicopter, paramotor, microlights - everything except military and autogyros.
Glider aeros are an art but the best flying is mountain soaring (french alps).
And if you get bored you can always tug - cable drop downwind at 50ft doing 250 kph followed by pull up to 150ft and land opposite direction - rolling the wings level from a 40 degree banked turn at 20ft.
The CAA stopped glider racing finishes after a photographer was decapitated - now that was exciting flying.
