As such, the demographic is more mature and serious about their concepts, characters and stories.
Transformers on the other hand is more Sci-fi & Fantasy, which we don't take that seriously... we generally take to it in a more child-like manner, immersing ourselves in the fiction elements more than the factual ones.
As such, the inconsistencies and contradictions are less important to us, because the easy enjoyment of the toys and the story is more fulfilling than trying to make sense of flaws (that aren't based on anything in reality to begin with, so can be difficult to explain).
This is why a joint convention wouldn't really work, as Transformers fans are more carefree and willing to leave behind their maturity for the weekend, while GIJoe fans would be more grounded in the rationality behind their Universe.
(from what I've observed at least)
