You will always find someone who says their way is better. Some truthfully are better, some are just opinion.
When making decisions about your exercise, don't be quick to jump on bandwagons and let other people tell you what to do because we're all different. Some questions to ask yourself: What is your current level now? (Beginner, intermediate, or expert) What are your fitness goals? (Weight loss, toning, body building) What are your limitations? (Bad back, lack of education, morbid obesity) Since all of us have different circumstances, we should all have varying exercise routines.
Given what you've told us, there's absolutely nothing wrong with using the machines at Planet Fitness. It's an excellent place to start. And for some people, that's all they need and want for exercise. If you want to grow, improve, and see dramatic results, you may want to change up your routine. But you do that in time. You don't have to start right out the gate.
For when you do decide to move onto body weight exercises and free weights, I suggest educating yourself, maybe saving up for a personal trainer session, and add a few different exercises into your routine at a time. I get ideas from watching other people at the gym. You may even strike up a conversation with them at some point. Avoid the all or nothing outlook. You can mix and match based on your circumstances, abilities, and goals.
