I have a good gaming PC, but I'm personally going to buy most of my new multiplatform games on PS4, for the near future.
I just pop in a game, it updates itself, and I can play it. Looks pretty much the same as if I was playing on "high" settings on my PC, with a nice smooth frame rate. I have almost zero problems with things like tearing, or pop-in, or graphical artifacts. Saves are backed up automatically. I can take video recordings of gameplay with a button press, listen to the game's audio via the DS4's 3.5mm jack when I have a need for it (maybe my wireless headset needs a charge), and it's just a generally enjoyable way to game.
The PC can be a hassle sometimes. The platform certainly has advantages in cost, and tweakability (yay mods!), but when I get home from work, the last thing I want to do is fix a computer problem. Sometimes everything works fine, but the likelihood that I'll have to tweak settings and solve some kind of puzzle to get things running correctly, is really high. With my aging PS3, there was at least the payoff that eventually the game would be running at nicer looking graphics with smoother FPS when I was done, but that's not currently the case right now. The gains are going to be pretty small for a while.
