Game Maker 7 was very good for the time.
Game Maker 8, however, introduced some rather dumb problems. Regardless, I used it a lot back then.
I think most of my time was spent with GameMaker Studio 1.x though; perhaps even 1.4, despite it being absolutely terrible.
I got so accustomed to its problems that I stopped noticing them after a while. In hindsight, it's impressive I managed to put up with it.
GameMaker Studio 2 might be the best version so far; though I haven't used it much and I also have no intention to due to their subscription model.
So my vote goes to Game Maker 7.
