My all time favorite is the Wings of Power mustang. I estimate (dont kept a logbook in fs9) i have >1500 hours in it. For FSX i have spend most of the time in the aerosoft f-16. But with the update for the A2A mustang it is the mustang again. Also the speed is just right so i can use tileproxy with high detail resolutions.
Kind regards,
