They all pale in comparison to spilling doe estrus urine on your clothes. Trust me on that. 
 

But Gulp! baits are kinda stanky. 

I like the original smell of power worms. It is kinda stanky, but after catching numbers of Bass over the years on power worms it kind grows on ya. Now when ever I open a fresh bag of power worms. I gotta git me a big ole snort and sniff off of that bag. Now let me tell ya about the taste... I bite down my 7" & 9" power worms. Usually just take about a inch or so off.

I'm agreeing with everyone that said Chompers. Some real stinky stuff.

Of the pre-scented plastics I use - I'd agree that Gulp is the stinkiest...followed closely by Powerbait.

I agree about the garlic.

Chompers Garlic and Max Scent are both pretty vile.

 

Don't spill your spike it or JJs magic - good way to ruin things permanently.
