Experience with one UI 8.0 beta so far.

[Kshatriya7]

1. Fonts seems to have changed a bit 

2. The Now Bar ( live notifications ) works on lock screen with third party apps like Google dialer too.

3. No major visual overhaul 

4. Device lags a bit while scrolling heavily.

5. Battery is doing ok but definitely weaker than one UI 7.

6. You cannot archive the apps anymore as of beta 1. 

7. Weather app is a step in the right direction. Good work.

8. The notifications look much better to me.
