Personally, I would pick a culprit moccasin over any senko or yum dinger any day. Cheap for a pack, they last and I'm killing them on it here in Florida.

Rage Tail Recon Falcon Lake Craw

My favorite worm of all time are the Mann's Augertail worms in Electric Grape. I've fish them for years and they still catch me fish!

Zoom Trickworm watermelon gold flake.

At this very moment, my favorite is a Powerbait 7" Power Shaky Worm in Pumpkinseed.  The main reason being that I sneaked out of work early today and hit up a couple local ponds.  No monsters, but I caught several nice fish in the 12-14" range.  I had it wacky rigged with a Gamakatsu FIness Wide Gap hook and no additional weight.  It also happened to be the first time I've caught bass on a plastic worm, so that might have something to do with it.

Powerbait 7" in pumpkin green or blue fleck.

5" Senko in Junebug is my all time favorite, close seconds are Havoc Juice Worm Jr. in California, and Zoom Shakey Head in Watermelon

Culprit 7.5" Fat Max in green pumpkin.

Zoom Trick Worm in white or watermelon candy rigged weightless w/an Owner 4/0 straight-shank worm hook.

Zoom's U-tail in gourd green works best for me, texas rigged w/ 1/8 or 3/16 oz weight.  weightless texas rigged Senko 4" or 5" in Watermelon/copper flake orange are my 2nd choice.

River Rock Baits 5.25" Stick in Black Neon or Penn Melon Flash, those are the real deal.

Zoom Trick Worm Watermelon Candy 3/0 or 4/0 round bend with a 1/4 oz bullet weight

If I don't include stick worms, it's probably a toss up between zoom trick worms and rage tail recon worms

I don't fish worms much anymore, but years ago the powerbait ribbon tail in tequila sunrise was a killer! We would rip thru a couple packs a day, and go home stinking like powerbait.

Overall, Zoom is the brand and watermelon or green pumpkin magic red are my most used colors.

I do like zooms a lot but they seem flimsy to me.

Berkley Power Worm Red Shad -- Culprit June Bug -- Wal-Mart's Old Renegade Tequila Sunrise still got plenty of 'em.  

Grande bass rattlesnake in junebug red flake

Clear water:  5" Senko (Bubble Gum) 

 

Stained:  5" Senko (Plum w Emerald Flakes)

I'm split between two colors:

 

Watermelon Magic and Hot Pepper Frog (BPS Stik-O).

 

They've been "money" colors for me, but there have been a number of other colors that have caught me lots of fish.

GYCB "plum apple"

Bass Pro stick-O 4.25'' in Blue Craw and Trigger X Hammer Worm 10'' in Purple Shad.

Mine would have to be zoom finesse worm in watermelon red. I have not been fishing long but i have caught quite a few on these.
