Benzadmiral, I found an old bottle of the Eagle One (silver bottle with blue label) and love the stuff. Try not squeezing the trigger all the way, it seems to water it down and reduce the suds. Just a slow half pull and it seems the best. I like the stuff, but maybe that is because I really like the parent company! But, I have the Eagle One gel wax I found a while back and like it as well.
I like the way you think. Wax is kind of just wax so why not get the one that is the least offensive to your body, whether it be burning your cuticles, smelling bad, or just being not fun to handle. I don't think my eyes can spot a difference of waxes. Techniques and types/conditions of the cloths and mitts I might be able to sometimes, but probably not the wax.
Technique, I don't think you are every supposed to draw a circle with your applicator. Maybe do a figure eight or a side to side back and forth motion, but not a circle.
