Are you strictly focused on running/walking, or do you require a variety of resistance training to meet your health objectives? Conclusion

Do you have the square footage for a bulky machine? Can you afford the initial $1,000–$3,000 investment for a durable treadmill?

Ultimately, the "better" option is whichever one you will actually use. A treadmill is a superior investment for the time-crunched, goal-oriented runner, while a gym membership is better for those who value variety and the social atmosphere of a shared fitness space.
