owned a 2015 M3 6 speed for 3 years (stage 1, springs, spacers)
just bought a 2021 M2C DCT last week

the cars are very similar. But the M2 is more fun and nimble to drive around town, even though weight is similar. the power band feels more linear and you want to rev it out. i never got that feeling in the m3. i actually removed the stage 1 93 tune from my M3 and put the CS tune on it

ride is a weird one. i think the m2 rides better around town. just feels... better damped. Bumps are just 'one and done' and not 'crashy' like my M3 was over small imperfections. My M3 was lowered on swift springs and had spacers though, so the geometry was altered. maybe a more fair comparison would be an m3 comp and m2 comp. M2 ride quality is similar to my GT3, and i prefer it over the M3.

on the highway the m3 is better. much less NVH and wind noise. long wheelbase stability.

seating position is better on the M3. You can get lower down and the car is lower overall. but the seats are pretty much the same. m3 gets nappa leather, m2 gets dakota (rough) leather.

stereo is slightly better in the M3. M2 isn't bad though. no complaints from me.
