I'm not a fan of the new city bars either. It's way too cluttered for my tastes.
I prefer them, but generally only with cities that have short names. It's a fairly good use of space overall, but feels cluttered when the governor icon is added (I hate to think how it will look when cities have a religion as well). Not a fan of the gradually-filling production icon which can make it more difficult to see at a glance what's being built.
It's going to be hard saying farewell to faith purchasing units, but I can't
If this is an intended change it's probably good overall, but there needs to be some way to more usefully use faith if you don't have a religion (or just more ways to benefit from having/spreading a religion that spreads to you). Faith already suffered from being too marginally useful for non-religious civs (and by extension at higher difficulties where non-Arab civs will rarely if ever get a religion), as it falls into a weird space where the few non-religious uses for it - mainly GPs - require higher faith production than you can usefully justify in a nonreligious game.
If you click on the city population "circle" on the city bar it automatically takes u to the "manage citizens" view... VERY good change!!!
I can't help feeling it would have been a better one just to combine the city views into a single traditional Civ-style city screen, as the CQUI mod does. It's disappointing that they didn't make minor quality of life changes to the interface that the existing mods demonstrate are possible - such as the city screen or updating the pins to display at least the appropriate district colours, if not the full set of Wonder icons.
On the last livestream, they even specifically pointed to the military report option available from clicking unit names, but they failed to add a proper military report to the Reports screen, and aside from adding the Reports icon they haven't made any improvements to the utility of the reports pages.
The new alliance system also seems to make it more important to have something akin to the old Civ I-IV relationship network available, but that hasn't reappeared either (a Civ V mod implemented it - not sure if there's an equivalent in Civ VI).
