I have used Jim Stepp's steps since they first came out. For preset platforms they are fantastic. The only thing I didn't like them for preset platforms is they are easy to see and give away your location.
For run and gun.... I do NOT like then for a platform as they are difficult, in my opinion, to set around a tree at hunting height. Can be done but awkward at best, especially if tree leans.
For climbing trees I found them to be a pain in the rear and noisy in the dark. Getting them in and out of the bag is noisy. The ropes are also a pain to get in bag. I switched all but my presets to amsteel which worked far better for me. The rope supplied used for presets is fine and squirrels don't seem to bother them.
I have tried Red's method once and it was great going up but coming down was awkward for me. But I was on a leaning tree and that complicated things. I'm sure with practice it can be a great climbing system.
I think any system has pros and cons and can work with enough practice.
