3970 - Because I never got into the 5970
I bought a 5270 a few years ago, intended on looking for a 5970 but the prices were very high, so 5270 it was.
I have tried on the 5970 extensively, on one occasion I tried it with the 3970.
For me, the 3970 was effortlessly more charming in gen 2 guise. It truly is a magnificent piece of watchmaking and the smaller case appeals to me.
The 5970 is trying hard and does get everything right, its virtually faultless but there is just something about the charm of the 3970 that really does it for me, perhaps its owning a 5270, that smaller, vintage size...
So neither are an incorrect choice, it perhaps comes down to wrist size, preferences and what else you own.
