For PC the controls are not intuitive and it takes several screens to see what they are as the default view of the controls is an Xbox controller.
The save system is a joke.
Cars disappear, no point in upgrading them.
But the story is interesting, at least with Michael and Franklin. I don't care for Trevor, can't wait to kill him in the end. The world is fun to explore and since you don't have hidden loot in every single building it makes it less of a chore to explore the world.
