Honestly, it depends entirely on what you race.

The Instinct is a dedicated Formula position rig. If you strictly race F1 or open-wheelers, it's sick because the immersion is spot on. It handles high torque/Force Feedback from Direct Drive bases surprisingly well without flexing, so stability isn't an issue.

However, the upgradability is kind of a pain compared to an aluminum profile rig. Because it uses custom tubes, you can't just easily bolt on a shifter, handbrake, or button box wherever you want—you're stuck with their specific mounts.

Also, if you ever want to drive GT cars, Rally, or standard road cars, that "laying-down" position is gonna feel super weird. If you want versatility, I'd skip it. If you only want Formula immersion, it's a solid buy.
