touch performance comparison for various versions of ESP32

Hello, I've been experimenting with ESP32 and its touchpad capabilities (in particular using ESP32 arduino library examples), and would like to know if there's any hardware differences between ESP32, ESP32-S2, S3, or any other versions, and whether any of them is better in terms of hardware.

I've taped a 1mm plastic to the top of the touchpads using ESP32, but I've unfortunately only been able to get roughly 3-5% difference in reading, making it maybe harder than I'd like to identify touch events. Does any of the other chips perform better?

just bumping this to see if anyone with information, would love to figure out if I can use another esp32 chip with better touch performance.
