It really depends on your usecase, your experience, even your hand size.
I had a few very concrete pain points, but a 60% wouldn't have solved some of them either.
I hate the position of right shift, now my shifts are symmetrical.
I hate the modifiers, using alt, shift and ctrl in quick succession is common to select and move words, now I have all modifiers on the home row, it's much easier when I have to combine them.
Backspace on left thumb is extremely fast, also j + bspc combo for delete word.

I just hope people with similar usecases would look into it, and not be dissuaded by memes alone. You can also get some of the benefits with software remapping.
