I thought it was interesting because unlike other comparisons I've seen it was someone using a high level language going to "lower level" ones. Like any comparisons there are a lot of different ways to do thing (even python...), so they'll always be "we didn't they use this or that". And frankly there are very few of these comparisons written by experts in all the languages (usually its someone writing up there experience). For example's one might complain, he's comparing speeds using "Pillow" which seems to be a c -library wrapped for python, but honestly that's how one might do it, ands its pretty easy, so its legit to me.
