We're finally redoing our 2.8" resistive touch screen shield https://www.adafruit.com/product/1651, which has been out of stock for a looooong time due to parts shortages and then TFT pricing nuttiness. This time, we're revising it to use the TSC2007 https://www.adafruit.com/product/5423 and testing it against the new Metro ESP32-S3 prototypes. We've wired the IRQ pin-up, and the touchscreen responsiveness is excellent. One nice thing about using I2C is that we don't have to share the SPI port, so if you're using something like LVGL, which does TFT drawing or touch screen reading in an interrupt, there's less risk of contention.
