In my experience the minimum hardware baseline for Firefox is higher than Chrome but the optimal hardware baseline is lower.
I switched to Firefox on Android a few years ago and it was unpleasant until I upgrade my phone. At the time I was running a Nexus 4 and moved to a Nextbit Robin.
My partner switched to Firefox on a Google Pixel and regularly complains about issues with it's performance which makes me wonder if Google has done some optimizations to Chrome on the Pixel.
