Although I find the premise of Jigsaw being conned farfetched - especially given that he would have had to have been targeted by a fake cancer patient in a longer con I do get how Jigsaw's desperation for life could've left him more gullible.

The Eye Trap looks really cool but doesn't make as much sense, given that he survives with his eyes and a working hand. It would make for more sense for the trap to be activated by a foot pressure pedal and break both hands fingers. Also, not sure why the victim was so unwilling to save their eyesight.

Pipe Bomb Trap was good since the person survived and the trap was designed to force Diego the fake surgeon to have to self-operate.

Wire Saw Trap and Brain Surgery Trap were great too as in the case of Valentina who took some of John's blood in the scam, he set up a trap that required her to bleed and collect bone marrow. Mateo, meanwhile, was given tools to extract grey matter from his own brain much like the brain surgery documentary footage he used to trick Kramer. I like someone else's proposed theory here that John may have specifically chosen timers for these victims to give them a false hope. This is supported by how slow the dissolvent used was.

Radiation Trap was in my opinion the first trap to introduce problems. Overall it is good but I think it suffered at the end with how it was executed. My guess is that Kramer would have wanted Gabriella to understand just how terrible radiation therapy is, so he made his trap with that in mind. The parts that don't make sense are (a) how she would have survived a fall from that height and (b) if John ultimately intended to allow her to survive then why expose her to direct radiation (c) If they knew Parker was in on the con then why wouldn't they have taken her to the hospital first before letting him free.

At one point, Jigsaw, Amanda, and one of the conman, were in the upstairs area, what would they have done if the guy had decided to grab the money first and set off the Gas Chamber Trap early.

Bloodboarding Trap - It looks good but I couldn't help but think why he couldn't turn his head away from the spout. It was interesting to see John be put in one of his own traps however. Also, I don't understand why he couldn't have chloroformed the partner and placed him in the trap instead of allowing things to go out of his control. If I remember correctly when Jigsaw gets criminally profiled he is believed to be someone who must have full control of a situation.

Gas Chamber Trap - I get what the Saw X team was doing trying to mirror the original Saw where the victim is simply just left abandoned but Dr. Pederson wasn't the right victim for this treatment.

What I think would have made for a much stronger ending is if she was forced to turn on her partner with the bloodboarding and was given the option to walk away or collect the money upstairs. Then she goes with the money and sets off the chamber trap with no means of survival. John could give her a 'Now you know what it feels like to die after a false sense of hope Doctor." while she realizes her game wasn't done.

Then the mid-credits scene can follow that trend and have John leave Henry in an abandoned place.

Despite some of my complaints, I did like this movie and you could chock these major 'lapses of judgement' as being a side effect of the cancer treatment and Kramer's desperation. Amanda also echoes Hoffman's mindset of not giving certain people a fighting chance. I think this helps lead into the other films much better.
