Yeah that's a good summary
philm
Yeah, but unironic...
If your code needs comments, it's either because it's unnecessarily complex/convoluted, or because there's more thought in it (e.g. complex mathematic operations, or edge-cases etc.). Comments just often don't age well IME, and when people are "forced" to read the (hopefully readable) code, they will more likely understand what is really happening, and the relevant design decisions.

SUUUUUUUUURE!!!11 I"M oN ITTTTTTTT
We're at 22.8̅2̅8̅7̅8̅4̅1̅1̅9̅1̅0̅6̅6̅9̅9̅7̅5̅1̅8̅6̅1̅0̅4̅2̅1̅8̅3̅6̅2̅2̅% slowly gaining rainbow ground
I just calculated exact subpixel accuracy, for me it's exactly 20.5̅9̅5̅5̅3̅3̅4̅9̅8̅7̅5̅9̅3̅0̅5̅2̅1̅0̅9̅1̅8̅1̅1̅4̅1̅4̅3̅9̅2̅0̅ % that is still missing to fill the whole comment body with rainbows, way to go!
Let's start the sixth rainbow!
Plenty of space for me still (browser version on desktop)
Rookie numbers, it's probably 15% on my screen, There's space for a lot more rainbows
"easily" solve it.
FTFY
I mean if you have a super nice working environment (team etc.), I don't see an issue with staying at the company.
But yeah as you say, if the new company is better in every single way, of course you should move.
Don't get me wrong comments != documentation (e.g. doc-comments above function/method).
I probably was a bit unprecise, as others here summed up well, it's the why that should be commented.
