Which one is better? Onkyo DRS2.2 vs HTR510

I have a set of Bose Acoustimass 600 (5.1 cubes) and would need to get a receiver to go with it. I am looking at the DRS2.2 (40w, 5.1, dvd w/receiver from Envision 950) and HTR510 (100w, 6.1, receiver from S760 package).

details are here...

Main differences I can tell so far from looking at the specs...

DRS2.2       &n bsp;  HTR510
======================================
5.1ch/40w       &nbsp ;  6.1ch/100w
no WRAT       &nbs p;  WRAT
PS DVD       &nbsp ;  Just Receiver
Japan Made       &nbs p;  Malaysia made
Programmable Remote       &n bsp; Normal Remote
no DTS Neo:6       &nb sp;  yes DTS Neo:6
30-25khz       &nb sp;       20-20khz

Assume both are around the same price, which one will be a better reciever/sound for the bose system i already have? Many thanks!!

Btw, for some reasons, the retail for Envision950 system is ~$900 while S760 is only $500?!!
