I've had both the Port-A-Steps and now the Torklift Glowsteps. Kind of a toss-up between the two, I guess. The Port-A-Steps are great if you stay in one place for longer periods of time since they take a little longer to set up and take down and require space to store them when traveling. They have a nice hand rail and a 24"x24" top step. The ground supports are longer allowing more adjustment capability on uneven terrain. Glowsteps stow easily where the old steps were and have a slight edge on build quality. When I had an offer to try the Glowsteps, I did and decided to stick with them for the kind of travel we do(multiple short stays). Now I have a 4 step Port-A-Steps taking up space in my workshop.
