I've not faced any audio sync issues so far.I watch Netflix quite a lot more than I watch Prime. Prime often have audio sync issues to the point I have sometimes had to find 'other' ways of watching the show. Prime also seem to sometimes give the first X amount of seasons for free, then want you to pay for the most recent season, which is not good.
Unfortunately different companies are wanting to make their own streaming service, like Disney, so both Netflix and Prime might lose access to more shows. As said, Netflix have more and more of their own content though, which they can't lose unless they cancel it themselves.
I've not watched a full season of anything yet so I've not faced this yet but its good to know, Is that the case for all shows ?
Netflix is a lot better for content and how often its updated, but then Prime has more to offer than video content..... So would not really be comparing the two together
I would agree you cant really compare them at this point,I started with just Prime 3 or 4 years ago, and was really happy with it, but got Netflix a year or so after (Mrs cheesyboy wanted to watch The Crown): I would say it's now split about 80:20 in viewing time between the two, in favour of Netflix. There's just a lot more good shows on Netflix. And it's easier to find new stuff, without Prime pushing paid content at you all the time.
Prime Originals are not as good or as varied as Netflix Originals. I'm not sure Amazon even has any original adult (western) cartoons, for example. And if they do that's another illustration of the difficulty navigating the library.
Movies selection seems similar, but I don't watch a lot of movies.
Netflix has varied selection of original,. I was surprised they even had some excellent original cartoons so you can enjoy them with the kids.
So far Amazons originals all seam very similar no variation like Netflix it does has some exclusives from other company's preacher (AMC) but you can say the same for netflix.
Outside the originals I would say prime has more choice which stays on for longer in terms of movies and show but that could the case of what I like but most of the time when I search for a movie or show Netflix does not have it,
I would say netfilx has a lot more exclusive content, but prime to have a wide selection of good non original show and more movies.
I would say if amazon never came out with the monthly package I would never use them.
