They are more expensive. Because the lock-in isn't as tight.
I still like them because, ironically, for sporadic printing, they're more resilient than many ink cartridges.
So far, I haven't experienced any clogging (dried up ink in the print heads) or the printer resorting to ink consuming processes every time it's turned on after not having been used for a couple of weeks.
This is after some years of usage where I've refilled the tanks once.
Not great. They still clog, the printer still wastes a ton of ink on cleaning or adjustment or whatever. Last time I had one I woke up one day to find that all of the yellow ink was gone. Several ounces of ink presumably dumped into a sponge inside the printer. I chucked the whole damn mess in the trash and bought a Brother laser printer.
