Last year I upgraded from a early 2013 15" MBP to the 16" Max and it's like a whole new world. Way more storage and memory. I can imagine going from the same machine to the M2 would be amazing but from M1 to M2 not enough of a bump to pay the price.
M1 generation -> M2 generation is a pretty small difference, not something you'd normally notice. In my experience unless using a stopwatch or running benchmarks folks don't usually notice improvements till they get into the 1.5 to 2x range.
