My last several blu ray players have been Panasonic, as well as plasma tvs. But at this point for the reasons you mention and in the sub $100 range, I'd go for that sony. It also has the miracast feature that the 91 panny doesn't, which might not mean much to you, but any youngling with an Android phone or tablet will definitely appreciate. Panasonic needs to get the sales message also that stealth ads, even on entry level products, is not acceptable. At least, e.g., kindle sales warns you and lets you save on the sales price if you opt in.
Edit : many blu ray players, particularly the cheapo ones, seem to fail one or more specific av tests but otherwise do more than reasonably well for pure blu ray playback, so wouldn't stress that so much. If your doing a lot of DVDs and upconverting,that's where you spend the extra bucks for an Oppo.
