I think you would agree the second were in fact the safer planes.
Now those Nimrods will have had a huge amount of hours on them and would also have undergone rougher treatment than most civil planes being as though they are military.
Without knowing what hours they have flown I would guess there safety record would be at least on a par with many civil airliners.

Therefore the risk factors were greater, and needed greater mitigation (which didn't appear to happen). If you know something is old and needs upgrading/fixing, it doesn't lessen the blame if this isn't done (and if you read the inquest reports, a lot of "known issues" are coming out of the woodwork).
