(To be fair I only carry two tubes, sometimes three, so it's not like I could make it past 2 flats no matter how I inflated them, but still.)

I also favor full size pumps due to never running out of air. A few times I've had a slow leak, and rather than change the tube, I've quickly topped it off with the pump a few times to finish the ride.
Another time, I had 3 flats, but 2 tubes. For the 3rd flat, I found some plastic bag litter & wrapped it around the hole 4-5 times. It held air for a week !
I've also bailed out a few riders that ran out of CO2.
I'm fortunate to ride a mid-size frame, so a pump fits nicely under the top tube. The Zefal & Blackburn pumps are nice.
Park makes an adjustable full size pump so it can swap easily from road bike to mtn bike (and has a reversible head).
