I do have the non-electric Go and it is not a problem. When I first got it, it was kind of hard to turn but then has gotten much easier after a short time. I cannot talk of the Circuit Air - but I am sure others will be able to tell you something.
You said you are a Senior - I am 61, so considered a senior too. And I have arthritis in my hands, not severe but it is there. I do use the June Taylor Shape cutter too, but prefer my Go when doing a lot of cutting.
