With quality lenses I can agree. However, my Canon 1D MkIII vs 1Dx MkII being about 9 years apart are very different in capabilities. Both can take nice photos but the MkII is head and shoulders above the prior flagship model in many ways. Frankly the MkIII rarely gets used unless I am shooting in good light and want the advantage of the 1.3 crop factor. But that said I have images taken with it in the past that I cherish.
I would encourage people to buy the best gear they can, learn its capabilities and enjoy what you have. Every piece of gear is a compromise and there will always be something newer coming along.

Just my opinion, but I think the importance of gear is limited, except for a lens. A quality camera and a quality lens bought 5, or 10, or more years ago that provided high IQ when new will still provide the same the same IQ, unless it's been dropped off a bridge or something.
