It really has been trial and error to find the optimal combinations. To make it even more confusing is the reality that different people using the same razor find that completely different blades work best for them. Throw in adjustable DE razors, and it gets even more complicated.
Very true, there's a lot of shave forum based geekery involved, but DE isn't the only format so afflicted. I found out, after some minimal trial and error with a handful of different blades, that I am quite happy with Feathers in every DE I've tried (lots - from the original Fatboy circa 1963 to modern Wolfmen). But the humble straight has also been bred beyond the simple 5/8 Red Imp and barber's hone, to 8/8 cleavers whispered to sharpness by stones from a particular cave, or leather from the right butt cheek of andalusian equines only ..
