Not better - different.
They are small, but EASILY grasped and let me put an effective shower of sparks exactly where I want it. I have one in my pocket as I type this - it is EDC for me, clipped to a tiny polymer frame lockback knife with a Fastex sort of quick release. It is always in my left front pocket.
This particular Hot Spark has started hundreds of fires - I have used it at several council and district level events to teach scouts and scouters how to use a MFS to start fires. Plenty of life left in it. Of course, when I do wear it out, I have a stash of them ($1.90 when I bought them).
One thing that is easier to teach/learn with this particular style MFS is to put the scraper edge where you want the sparks and then PULL the Hot Spark away. Scraping the edge down the MFS may make a pretty shower of sparks, but they are distributed all along the length of the MFS and is what everyone trys to do naturally with conventional MFS rods. Hold the edge still and pull the MFS back - presto, all the sparks in the same spot. And that is really easy to learn with this style of MFS.
These things are small but work great. A Hot Spark, suitable scraper, and many vasoline impregnated cotton balls fit in a SMALL Altoids tin, which is how all my scouts carry theirs. Ranger band from a bike tire holds it closed and keeps the whole thing mess-free. Learn to use one and you'll swear off matches and lighters for routine fire starting.
