Joy, what a great question!
I believe your question can be answered in a myriad of ways.
1. Just because the equipment is large doesn’t mean that one has to use heavy loads. It simply means that a piece of equipment is large. Usage of the large machine with variable resistance may be the best option until a person can use their own body weight as resistance. A fixed machine with variable resistance may be the ideal piece of equipment for someone with limited strength.
2. What is your goal? Is it a health goal? Is it a performance goal, or just a fitness goal.
3. Are you training for brute strength or are you training for strength endurance, or strength stability.
4. What do you prefer body weight training or training with equipment.
In my opinion, the best choice is the one that you will do on a consistent basis, that you enjoy and that helps you reach your goals.
I hope this is helpful to you.
