I thought the same and also had the same doubts. Bought the EZ cap to test it out since you can either do the swing top or caps with those. I eventually ended up ditching all the swing tops.
Some of the cages got wonky on me after a while, the gaskets need replaced, bottles can be harder to transport with the wire, and if anything goes wrong with the seal it can be hard to tell until it just...doesn't carb. It was much easier to tell if the capping was done correctly. That was my experience, at least. Just swinging the tops over at the start felt easier but a good capper goes a long way to closing that gap.
They can also be intimidating for many people trying to open them. Maybe not a big deal but if you like to share it was shockingly common that people didn't know how to do it or just...lacked the fortitude

People would call me to ask how to open the bottles.
