As for bass quantity: yes, it is of course a matter of personal preferences
And to a very significant degree for some of the headphones mentioned in this thread, a question of effective coupling with the individual's anatomy
.
For over-ears, Rtings measures the bass response, up to a few hundred hertz, on five real humans :

The K371's consistency across individuals is rather poor in terms of bass response :

(Not surprising, for a start its hinge design is idiotic and lacks basic range of motion to properly conform to varied anatomies).
There's also the question of variation for the same individual depending on positional variation and head movement. You can read about my own experience here :

If you want to dig deeper, an article on the question of leakage from Harman :

So this is a bit of moot point debating about the K361/K371's bass response without knowing the actual response that your sample manages to deliver on your own head
.
While I can't speak for someone else, I can already say that, for me, the NTH-100 holds a very significant advantage over the K371 when it comes to its capacity to deliver a consistent and repeatable FR. It's too bad that the basal FR it delivers is rather poor, but since the main use case for them for me is in situations where I'm going to use them with the Qudelix 5K, which has a ten bands PEQ, it's fine.
Unless, of course, solderdude measurements are off (which I do not believe).
There's always going to be
some difference between the relative measurements you see on an ear simulator between two samples and the effective, on head relative difference between your own two samples. Difficult to quantify how significant that difference is without extensive data about sample variation and variation across individuals.
At higher frequencies, Solderdude's test rig isn't as good an approximation of the human ear as ear simulators like such from GRAS or B&K, but even the latter may not perfectly represent how two samples would differ on your own head.
For me, my own samples of the HD650 and NTH-100 behave on my own head differently, relative to each others, from Solderdude's results, but the main "gist" of the difference is similar.
