I own an Onkyo TX-SR602 and I'm pretty satisfied with it. I'm using it in a smallish room to drive relatively easy speakers (8 ohm, 92 db). I never tried its auto setup, I tweaked it as best as I could myself. The lack of pre-outs (except for sub, obviously) is annoying, but may not matter to you; the Denon AVR-1905 does have pre-outs. It has more digital audio inputs than the AVR-1905, if that's important to you. The AVR-1905 up-converts to component, the TX-SR602 does not. Occasionally, I'll try to use the OSD on my TX-SR602 while using the component output, which is mildly annoying, as it can't do it; I think the AVR-1905 can. I don't know what remote the AVR-1905 comes with, but I actually really like the TX-SR602's remote (either way, you can replace a remote easily). I have not used the AVR-1905, so no comment on ease of use. However, the TX-SR602 is one of the easiest-to-use receivers I have used.
