There's the 'soft' cultural variation of expected work hours (duration and placement during the day), remote vs. in-office only, single 20 somethings that work all the time vs. mature family focused that aims to have a healthy work-life balance, star wars vs. star trek, etc.
Some of those soft things can really matter to long term happiness of both the employer and employee.
Then there's the critical 'hard' cultural variations.
Is it a culture of sticking with the tried and true tech stack and focusing on reframing the tech challenges to fit that stack? Or a culture where NewFunStack.js made by Behemoth Tech Company should be used?
Strangely enough I bet both sides of the debate would say they're a culture of focusing on "getting stuff done". I've seen people be highly productive in both approaches, so I'm inclined to say its more a cultural fit question than anything else.

Their differences have tended to be less in recent years as both franchises have become "cool".
