While I much prefer the 1015's amp design in theory, whatever advantage it has is not apparent when I listen. The differences in the pre/pro section are, though, and there the newer design has a distinct edge: Improved MCACC, DD TrueHD and DTS HD-MA decoding, etc.
As for raw power, the 10 watts difference in rated power (two channels driven at 8 ohms) is inconsequential (0.4dB max output). The 1015 does seem to have a beefier power supply, and would probably have an advantage if all 7 channels were pushing full output, but that doesn't happen in the real world.
I have meters, which help keep me from being too psyched out by published power ratings. I know that it is rare for any pair of channels to pull as much as 2w output in my setup, much less all seven at once. The loudest bangs may hit 10w occasionally when I crank things up, but either AVR still has lots in reserve.
BTW, my much loved 1015 is still serving in a second system where the new HD audio codecs are not an issue.
