1. Sharn. Eberron's vibe just really suits urban adventuring, and I like Sharn's verticality and size. I will say I want a better view of the city, a lot of maps and art doesn't really sell how the "city of towers" would work.
2. Sigil. I like Mos Eisley style campaigns where any PC species is an option, and Sigil really allows that. That said, this is an assumption, I've yet to play a Planescape campaign.
3. Waterdeep/Baldur's Gate/Neverwinter. Forgotten Realms has several major cities for campaigns and I think I like Waterdeep the most. Dunno, BG3 upended that and really showcased the city, but I've run Dragonheist so I got deep into Waterdeep's layout. And I ran a few Neverwinter adventures back in 4e. But I've played in all three and like them.
