Games on PS4 are way safer. It's like a restricted platform.
Comparing Rocket League's chat on PC and PS4 is enough to know the difference. While playing on your PC, you can quickly abuse/spam the other player because you have a keyboard to type on. Because PS4 only has a virtual keyboard, you don't have enough time to use the controller to type whatever you want. You have to use some preloaded custom messages like 'Nice Shot', 'Excellent Save!'
