Fox-a-flat says it doesn’t work below 32 degrees Fahrenheit. I carry a tire reamer with plugs and rubber cement that have always worked with slow leaks (punctures and what not). Fix a flat has failed a couple times for me and I think it ruins the tire. Where the plugs seem more effective at stopping the leak.
This is the one I have used a few times as I live in michigan with crap roads.
You can plug it yourself. Any department store carriers tire plug kits and I keep one in all my vehicles. Skip the ones that look like screwdrivers and splurge the extra buck or two for the T-handled ones like this.
Actually plugging the tire is really simple but it does take some physical strength to drive the plug in, especially if you don't want to pull the tire off. I've done them pulled off the side of the road multiple times. It's not bad. Oh, and keep an inflator in your trunk too so you can top off the escaped air once the plug is set.
Honestly, I don't think there is a huge difference between them. I would worry more about having the proper tool kit to be able to install them properly. You can either assemble this yourself or try to get a kit with everything needed. Here's what I bought but you can just go by Amazon reviews.
