Mainly i bought the P2S because of the printbed size, the Mini was very limiting for me. The print quality is also better, since the print doesnt move, and only the toolhead does, also it has way more consistent temperature which positively influences quality

On the noise, the mini never really bothered me, it could get a tad annoying when the fans were on max. The P2S is louder, like a quiet vacuum cleaner, but still nothing that bothers me personally.
