My 93 is the same in DLNA as pio bdp140 which I bought for 60 quid several months back. However DLNA does not provide ISO support so I am not bothered with DLNA personally but who does - you are unlikely find big difference between big names.
I can't comment on the pioneer player but I have a lot of experience with the Sony 2012 players with DLNA.
With the right mime types the sony players will support native playback with
avc h264 and DD, DTS, DTS MA in MKV containers
However when it comes to VC-1 and MPEG-2 these must be in m2ts containers.
When it comes to mp4/m4v containers with avc h264/AAC these can have audio sync issues. However in a MKV container - no issues.
The MKV support is generally temperamental on the Sony. Just one small network hickup will trip the sony players up, and stop playback. The sony players will completely lock up if you attempt to FF/REW a MKV. However M2TS containers are far more reliable and preferred.
Audio: AAC, mp3, WMA, FLAC, wav
Note - The Sony players don't provide any support for album artwork, shuffle play, (native) playlists.
I think you will find the Oppo players are a bit more accommodating and flexible.
I don't have any real issues with Sony and DLNA but you do have to work around the querks. Many people won't be prepared to do that and want something that works out of the box.
