I'm not familiar with Game Maker Studio.
A major benefit to Unity is the Asset Store. It lets you fill in gaps in your skill set inexpensively. I could spend months developing a responsive character controller, or I could spend $70 on one and focus my time on game content.
Not to mention all of the art assets: characters, animations, environment models, particle effects, etc. Sure, it's better to have custom art for your game, but if you're not an artist and can't afford to pay for custom built art then at least you can still make a game.
You could certainly build your game concept with Unity + ORK Framework. Your best bet may be to try both toolsets and see what works for you.
Unity has a larger community and thus you'll probably have an easier time finding help when you need it. ORK has a great community in its forum and it's a tool that is designed for building just this type of game.
