Not Marseillle I guess...
They share a lot, and Marseille is the "closest" thing to SF in France IMO, but still, it's different.
1. City Layout => idk what it means
2. Architecture => Different... Marseille is extremely old and ultra compact. I prefer SF, more open
3. Climate => Marseille is hotter, dryer... But with less sun / year
. Marseille has one default: it's very very windy, non stop. All year long...
4. Topography => They aren't flat, both of them.
5. Economy => It's comparing a cat and a lion, literally.
6. Culture => Well, Marseille has very old roots, starting in -600 before JC. They are quite different...
7. Transportation => I hate both I guess. marseille makes efforts, but could do much better.
8. Vibe => I like SF. Marseille has this "Naples" aspect, old -dirty for euro standards-, mixing ultra rich villas with view on the calanques and very poor ghettos, the most "dangerous" in France (Its not Caracas but there's fight between drug gangs)... I don't know SF for its crime.
Marseille is the french Naples. Cities with huge potentials, not always very well used... Little photos of marseille and SF, cause' I love pics:
I can't wait to come back to the West of USA
Edit: Oh, I forgot it, but Marseille has its little Alcatraz-like Island, the If Island with the If Castle:
