I couldn't try the OPPO before a bought it, but researched it thoroughly. Having had an OPPO DVD player I felt sure it would be a winner, the service from OPPO is second to none, through the order process to the quality of the product it's self was excellent.
The OPPO is a smooth operator everything I put into it DVD, DVD-audio, SACD, CD's, Bluray's and video files are played without a glitch. I now use a 5.1 configuration as this works better in our room than a 7.1 due to the seating locations; I have Bi-amped the front speakers which pays dividends when listening to music, better control and faster clearer transients.
The audio and video are a major step up from the Sony BDP-S350/OPPO DV-981HD combination I used before video just appears more 3 dimensional sound has a better snap and control at the lower registers is better defined.
I have since tried the Denon and Pioneer players that you mentioned just being inquisitive as i already had the OPPO BDP and found Bluray picture and sound to be similar to each other but the load times were just horrendous. DVD playback from the OPPO is in a different league sharper and panning shots are more fluid.
My Sony TV doesn't support 24fps but the OPPO appears to manage motion better than the other players.
If I were you I would go for the OPPO, while there have been a few firmware updates these are common across Bluray players to support the atrocious java code written by film companies, OPPO appear to have a firm grip of any issues and remedy them quickly. They also respond to support e-mails in a professional and timely manor.
I hope this helps you with your choice as these are always individual and emotional choices.
that's interesting to me as I have the same screen as you (by the way, do you still love the W2000? I'm still impressed with mine). I do notice the lack of 24fps but I would not change my screen for that reason alone.
