I agree, a true pump is least likely to let you down, but it's nice to have the cartridges along to expedite things if you're dealing with a large tire, or in an unsafe spot and need to get moving again quickly.
The 12v pumps might suit some folks, but not me. For one thing, you can only use them with a bike that provides the power. Bicycles, and most trail or MX bikes don't give you that option. They're also slow, and if it just doesn't work, then what? CO2 also gives a quick burst that might help re-seat a tire bead.
One or two of these hand or CO2 pumps can take care of your whole fleet, as long as you remember to bring it along.
The other handy option for non-fuel injected bikes is called a "chuffer". These are great for airheads and other bikes where it's easy to remove a spark plug. It's a pneumatic fitting that screws into the cylinder head, and an airhose just long enough to reach the tire. Turn off your fuel, and crank or kick your engine over and you have one big air pump.
After trying to inflate a tire with a hand pump in 100 degree unrelenting sun, I bought the cheapest 12v pump I could find, removed everything I didn't need (like the case), wired on a BMW plug, and have carried it since. Works great.
So far I've never had to pump up a tire when I had a dead battery.

Something folks may want to double check is power capacity with pump use.
I got a 12V Powered pump works great but has a tendency to trip the Acc Socket off because it exceeds the rated current the bike wants to see at the socket.
To avoid this I rewired my rear ACC socket to my Centech fuse panel and selected a 15A fuse section - works great.
The reason for this post is to "test drive" any 12V pump you have before you need to use it.
If your pump does trigger the shut off of the acc plug and you don't have a fuse panel you can still use it by wiring the socket to a fused connector and connecting to the battery.
Luckily for me i was fixing a flat in my garage and was able to correct the acc socket limitations or I would have been in an uncomfortable position trying to get the tire repaired.

I use a 12 volt compressor and have a bicycle pump as a backup. Both have worked well.
I've owned the slime pump for a couple of years. Fortunately I've never had to use it on the road but, as I do with all of my travel tools, I have used it in my garage.
Using my travel tools, I have changed both tires and the slime pump seated the beads with no problem at all. I was running it off of the acc. plug and had no issues with blowing the fuse
I mention "travel tools" as I have a well equipped shop but I still make it a habit of performing all maintenance functions at least once using the tools that I carry along with me. That way I was sure to iron out any problems or make improvements on the tools in the kit.
Having used the CO2 cartridges for years on my dirt bikes I'm aware that it will take several to fill a tire up to spec. I don't know how well they'd do at seating a bead. With the compressor you'll have an unlimited number of attempts.
Just my two cents
Slime makes a slick little set that includes the 12V compressor shown above and about three different cables you can use to power it up, including an SAE, direct battery for hardwiring, and little jumper cables. It all comes in a neat little bag that zips it all up. I have used it and it is great. Instructions say not to run it longer than 8 minutes at a time. It is perfect for motorbikes. Sell for about $29 bucks. I found mine at O'Reily Auto Parts Store.
I bought a 12v mini compressor at Wal Mart. Around $15 5 think. It took around 2 minutes to inflate a Metzler 140/80/17 to 42psi.
This sounded interesting so I went to look it up.. Somehow I do not believe this is what you were referring to. So can you tell us a link to where it might be??
