I think the bigger issue here is not that there are contradictions, nor even how many there are, but the mere fact that up until the point of the crucifixion the four Gospels remain primarily consistent with each other (for the most part—sort of) about the majority of key issues, and then once you get into the passion the contradictions suddenly start piling up out of nowhere and just keep on increasing until the resurrection saga at the end where hardly anything is consistent. It seems to strongly support the notion, held by Muslims, Gnostics, and many secular writers, that this part is the least reliable and most mythically embellished section of the whole saga.
This is not correct and you make it sound as if the stories of the crucifixion are all entirely different. That the are difficulties no one doubts but that does not mean that no reconciliation is possible. If you can be specific we can look at the accounts
