I have a Tadao in my Rapper and a Virtue in my Marq 6. I prefer the Tadao because it allows use of 4 eyes whereas the Virtue doesn't. I don't know what the differences would be for an Ego though. I know Virtue has had problems with their G6r boards killing solenoids. Something about the voltage being off.
Too bad APE only makes for a few guns. Their boards are the best I've used and cost less than Virtue.
