I voted Neutral but my actual answer is: it's important for it to be as high as possible given the setup's capabilities. I ALWAYS prefer the highest stable framerate available to me because it does always positively affect gameplay the higher it goes.
For instance, if I'm playing on a console hooked up to a TV that caps at the industry standard 60Hz refresh rate, then to me, a stable, evenly paced 30fps is tolerable, but 60fps is preferred if it's achievable and available as a choice, but I do not enjoy fluctuating framerate without variable refresh rate to smooth out screen tearing. If I'm playing on a capable PC and a variable refresh rate monitor, then I will make settings sacrifices to ensure any framerate that stays at or above 60fps, and if it's a competitive game with uncapped framerate capabilities,I will prioritize maxing framerate out.
It's important but I scale my expectations to the hardware available. I always prefer higher as long as it can be delivered without severe frame pacing issues or screen tearing, but I understand that certain hardware configs have strict limits.
