Every pixel I've ever had has been extremely responsive. My OG Pixel XL, my Pixel 2 XL, my Pixel 4 XL, and my current Pixel 6 Pro were always very responsive and didn't seem to slow down at any point. I'd imagine the OG Pixel XL is probably a little.laggy-feeling compared to the newest pixels but yeah; hate to admit it, because I don't like iPhones, but the Pixel series is like the Iphone of Androids - and only the good things about the iPhone being only manufactured by 1 company - it's the phone of the actual developer of the OS and gets lots of extra features first because of it, only stock OS apps preinstalled except for maybe a carrier app if phone is financed through them (I have the T-Mobile app on my current Pixel, for example). Super nice build quality, I've always ended up being tougher on my phones and the Pixels have held up really really well. Highly recommend them honestly.
