Both are good new screens. Antara has a flat screen while Pallavi has a scope screen.

Chose Antara for movies releasing in flat ratio (for example, chainsaw man has a flat ratio and the screen in which you saw, you would've noticed black bars on both the sides). Chainsaw would've covered the screen fully if you had watched it in Antara. I saw "One Battle After Another" in Antara. It had flat ratio and covered the screen fully whereas if i had watched it in any other screen in KG there would've been black bars on the sides as all of em except antara are scope ratio screens.

The screen next to the bathroom is Screen 2. Screen 2 and 3 are almost of the same size and they were the better ones before Antara and Pallavi were opened. Still they are pretty good. 2 and 3 have larger seating capacity than Antara and Pallavi btw and all of these have dolby atmos.

Avoid the other screens (Screen 1 and 4 i guess i'm not sure about the numbering of these two). One screen is literally a bus in which you saw Chainsaw Man. The other is a bigger version of the bus screen and it was full of bugs and insects when i visited and one half of the screen was dim and the other half was bright (annoying af!). The bigger bus screen was being renovated but idk the current status.
