For testing purposes, I've test burned both indoors (on a inverted tin can). Both are easy to light with a flame but the Coghlin's material was easier to light with just sparks. I used both the sparklite and a flint/steel. The sparklite material is about half as large as the Coughlan's and therefore doesn't burn as long even when both are fully spread open. No matter what the prepacked size is, I just use enough to start a fire and put the rest away. No use wasting it all. The waxy Coughlan's tinder leaves a bit of residue on my fingers after spreading it out and fluffing it though.

The Coughlan's tinder is easier for me to obtain so it's an open and shut case on which one I choose for my kit. In fact, the Coughlan's tinder is replacing the sparklight tinder in my Ritter designed AM survival kit.

Note: I also added a Photo LED to the kit, dumped the fishing kit, added a reusable zip tie, Gerber bag and couple of Bandaids. The waterproof container bag is supposed to be good for quite a depth of water but in practise it pops open easier than a cheap ziplock bag.
