It's worth the extra $280 for the Oppo if you want world class upscaling for your DVDs, although the Panasonic is no slouch at upscaling and shouldn't be to far behind the Oppo in terms of real world performance. The Oppo can also handle SACD and DVD-Audio discs, this is not a concern for 95% of users at this time. Both players are fast loading, and as you said the streaming ability is a plus. Looks like 2 marks for the Oppo (upscaling, SACD/DVD-Audio playback) and 2 marks for the Panasonic (price, streaming). Depending on your needs or cares this may be an easy decision.
