I've never been invited to a prestige lobby and I got to about 4th prestige legit on MW2. (Not the only CoD I've played.) And I've never run into an invincibility hacker. Also it seems from the feedback on the forums and in fact the bugfixes that Destiny's servers crash constantly, now I rarely get booted out of my matches when playing, but given the fact that it is a pretty widespread problem I'd say the networking probably isn't up to snuff. Which probably means that if there are any security measures the game makers themselves put in place rather than ones instated by the console itself then Destiny's would probably not be that great.
