I prefer the Kickeez modified trap pad over all others. It allows me to mount my gun the same way every time. It does a great job of reducing recoil, and fits my shoulder pocket perfectly.... Just my opinion... Dan Thome (Trap2)
I've had good experience with limbsavers. I was out shooting one day and was able to compare the difference. Shot me nephews new 870 with the R3 (limbsaver) pad and then my older 870 without one. Big difference in shooting comfort. I bought a new pad for my 870 and replaced the pads on my 90T and my XT with limbsavers. I use straight pads, just my personal preference.
My personal favorite is a flat TrapDude/Gooey, or Super Gooey pad. Just had one installed at the Spring Grand by Tom Larkin owner of the Stock Shop, excellent pad and excellent installation by Tom. I've used the Gooey pads for many years on my trap guns.
Gooey Pads used to be my favorite. Now, KickEeze are my favorite. Gooey Pads might become my favorite again. Both are good products. I do change pads every year or so and I have never removed one from the box that was not already perfectly fitted to my stock.
I have a couple Gooey's with 30,000 rounds of use, and all I see is just a little wear at the heal and toe. I switched to a curved Gooey, but I think either of my original 1" or 1 1/4" Gooey's would be good for another 30,000 rounds. They are soft and reliable, with emphasis on soft.
I like the Kick-Eez so much I bought out their entire supply of colored pads. Now all I've got are the bright red ones... Wished they still had the bright breen and orange one. Easy to spot my gun in the rack or if someon is hositing it up.
