have to compare the Shackleton to the B-50 in which case the

Yeah, but the B-50 was completely outclassed by the B-36 and look how
long _that_ lasted...
Meanwhile the Shackleton flew on until the 1980s, and the almost equally
ancient Canberra flies on still. When a design finds the right niche, it
can be very long-lived.
(Look at the C-130 and the B-52)
