Back to the OP. Jaap said "pretty good". He didn't say as good as it gets or better than brand X, Y, or Z.
From personal experience I know the M8 isn't a patch on my Canon 5D at high ISOs (or the Epson RD1 for that matter). The M9 may have improved high ISO noise a bit, but it still isn't as good as the competition (does it really have any competition?). However, comparative performance is, sort of, irrelevant if, in absolute terms, it is good enough. So the question should be "Is it good enough for my needs?", not "Is it as good as the best?". If it isn't good enough for your needs then don't buy one.
