The M2 and M3 are more evolutions of the M series. If you already have an M1 machine, there's no real need to upgrade. But if you don't, the M3 seems like a great device to get.
Eg: The M3 Max is a substantial improvement over the M2 Max in both CPU and GPU. But the M3 Pro is a moderate improvement at best compared to the M2 Pro.
