Single stations for home use
A single station does one movement, and it does that movement better than any combination machine. The path is fixed, the angle is matched to the joint that works, and you have nothing to balance. That is why these machines stand side by side in every gym: leg press, leg curl, pec fly, seated row, each on its own frame.
At home the sum works out differently. You are not going to set up a row of machines, so the question becomes which single movement matters enough to deserve a machine of its own. On this page you find the versions that can be placed at home, from leg presses and hack squats to separate stations for back, chest and pull-ups.
