2 different watches. Price gap is also quite great.
1. AP is a massive watch. Ingy is more subtle. So it can depend on how big your wrists are. For the ROO, 6.75 ~ 7 inch wrists required.
2. As with all reps, both needs to be serviced upon receipt but Ingy can go longer without one thereafter. Both will outlive the owener with proper care and timely servicing.
3. The AP is more ready out of the box than the Ingy, IMHO. But with the Ingy, frankenization is easier and cheaper. You can source for gen dials, hands and even movement. You can't do anything to the AP except luming and a better strap. AP gen dial (if you can find one) will not fit a AP @12secs.
I have had the pleasure of owning a modded Ingy (Jakub AR, lello Datewheel) and recently studied the AP@12 in close quarters. The AP is an impressive watch. Excellent replication which will deceive 98.25% of the world population 99% of the time. Its gonna be my next purchase. Black themes or maybe the safari
Anyways, you won't go wrong with either purchase though I'd bet that you will eventually own both at one point in time.
