With the PS4s webbrowser you can watch youtube videos too and...

-you can watch youtube at the same time youre playing a PS4 game by using Sonys browser. With the Youtube app its not possible 

-the image quality is also better in the webrowser despite only being 720p so this means the youtube app is only 720p too and has worse image quality for some reason. I am not kidding look closer, compare any video.

- Youtube in PS4 browser support annotaions and subtutles and stuff just like with the normal youtube in a browser on the PC.

I cant stand the youtube Apps by google they are so cheap and wattered down, doesnt matter if its on adroid on other TV OS's. Have you noticed it too?

I use the app all the time. I find it easy to use and simple to navigate.

I have never even opened the browser in PS4 so I cannot compare, but I'm very satisfied with the app.

you should try it out like i said you can use it during gameplay

I don't use it during gameplay, I use it for my kids to watch cartoons.

Also, I am 100% certain that the app has subtitles, as my kids use it to learn English from songs.

App have subtitles too and I'm not sure about the quality because here the video plays in 1080p.

App is faster to navigate too.

I can just use Spotify for music I may want to listen to while playing a game. Otherwise the youtube app is fine. I've noticed that the browser has some issues with RAM consumption as well based on my time with my roommate and his PS4, which makes me believe the app is simply the better choice. I have never seen the PS4 have to force close all open applications (which was the browser with two whole windows) with anything except the browser.

The browser overall gets a 6/10 from me. Hard to recommend.

I hate it. Same as with the WiiU. To use the app, you have to quit your game. But you can browse and view it! The only reason to use it is when you just want to watch hours f videos.

But the browser for the ps4 is kinda cumbersome.  Gotta use the PlayStation app to make it easier... but then you may as well use the phone's browser.

The Youtube app on PS4 is pointless, just like it was on Vita. The PS4 and Vita browsers are a much better option for doing anything youtube related on either platform. Sony should consider droppig support for the app the way they did on the Vita, because it reflects badly on the PlayStation brands ability to use the service.

Both the PlayStation browsers are way better than people give them credit for. I have not used a non PlayStation browser in almost a year now, and I have not had any issues.

It's not often that I would want to see something on Youtube while I have a game still running. But it's good to know if I want to watch a walkthrough video for a difficult or frustrating part of a game I can do it through the browser without having to quit the game. Then again, my PC is in the back corner of the lounge room and it's quicker to pop on to my PC to do that sort of thing.

I have no problem with the app, it works fine for what I want.

I use the app because navigating with my phone is nicer than the controller.
