Question about Elgato Game Capture HD60S+
Mmm I only stream on the PS4 and would like to improve the stream a bit, am I good with this device? Or is there something better?
If you really want to continue streaming ONLY on the PS4, then no such device will help you to improve the stream. It also depends on what you mean by "improving the stream". If you are willing to create overlays and use animations/transitions etc. for your streams, then you can do this with a software like OBS Studio or similar and integrate your PS4 gameplay via capture card. THAT would significantly enhance your stream. And for this case, I can highly recommend the HD60S+.
TL;DR: without a PC and streaming software, no device will help to "enhance" a stream from the PS4.
