There are trade-offs to all methods, with plain old object comparison, you pay the price right up front, i.e. a small performance hit. But the benefit is that the semantics are crystal clear.
With event subscription, you pay a different price many times over. You introduce subtle semantic problems. The most insidious, being what order events are fired and processed, especially when the events are also firing other events.
