At least theoretically, on a console you would have fewer crashes than a PC user using an average rig. This is just because a console handles programs differently than a PC does and the console version of the game is designed to the exact unchanging specifications of that console.

Basically, what I'm saying is that your PS4 experience has no bearing on the PC experience which does still include quite a bit of crashing. Really, a lot of crashing. I've got a pretty juiced up machine and I still get the odd crash during peak hours when I teleport into Mor Dhona for instance. I haven't personally experienced a Hunts crash because I don't actively participate in hunts, but I can see it. I certainly have crashed during Odin once or twice.
