I started using Mega-Strike last year. I really like it. I like the tube, and how it dispenses.
One caution though. You cannot store it, or have it out, in direct sunlight. If you do, it will melt (within the tube), and when you take the cap off it streams out. A quick dip into cool water, or put it back in the shade, will return it to it's 'vaseline' state.
I like that a 'little dab will do ya' on your soft plastics (whew - almost messed up there!). I also like the fact that after I apply it, I rub the small amount left on my fingers into/onto my hands. I believe it helps remove other 'smells' that may be on my hand.
Haven't used the smelly jelly, so can't comment.
I have used Kick N Bass in the past (and some again this year). It's very potent stuff, but sometimes hard to dispense or use. Recently, I've tried this:
Take a small rubbermaid (or like) container with a lid. I use one from the kitchen that seals very well (I considered this to be important - given how strong KNB is). I glued a scotch brite sponge (small rectangular one) both in the lid, and on the bottom. When the lid is closed, they should touch. I then doused both sponges with KNB. When I want to apply it, I simply open the container, put the soft plastic between the two sponges, and then massage it through the lid of the container. It applies it pretty well. I don't get it 'on me'. And the KNB is sealed up much like in it's bottle. Only item is that it takes quite a bit of KNB to coat the sponges enough.
