Opnion: NetFlix on PS3 is a bit slower but just as good as Xbox 360
A website has gone and compared the NetFlix service on the PS3 to that on the Xbox 360 and report back that things are pretty much the same. While the Xbox 360's version is a bit quicker with loading times, the PS3 version has its own benefits such as being able to go the browser and search to add a DVD to the queue as well as instantly watch it.
One thing, as mentioned in the video, the PS3 has a huge one up on is being able to go onto the PS3’s browser and search by title to add to both the DVD queue and the Watch Instantly queue, so being able to manage both queues would be made easier from the comfort of your living room there.
Apart from that, both are, indeed, pretty much the same in terms of browsing the lists of movies, rating them and watching them. Of course, the only real difference is just the layout. The 360s service uses the same setup as the Dashboard and the PS3’s is more proprietary to Netflix. When XMB integration hits next year, I’m sure that would be more proprietary as well, and will probably be its own program like Home or Living with PlayStation.
Now the question is, if you use the 360 solely for Netflix play, is the party mode really worth the extra $4 or so a month?
