Hi, I have an Apple TV 2nd gen. I use my PS4 to stream Netflix, Amazon Prime, BBC, etc... I've seen that when using AirPlay, (being the source an iPhone XS Max or MacBook Pro 2018), there is a little bit of a lag. Is it worth upgrading to a newer generation of Apple TV? I would consider the latest one, the 4K one; although I don't have a 4K TV, but better to have the latest if I'm buying something. Thoughts? Thanks!
