ccTLDs are occasionally less reliable than gTLDs- The rules for running a gTLD are significantly more standardised. ccTLDs (Country Code TLDs) afford the parent nation much more control. This was largely a sop by ICANN to give countries a sense of sovereignty over their online identity.
There are lots of horror stories out there involving badly administered ccTLDs, as the quality of the body chosen to administer each individual one varies so much.
At any rate, ccTLDs are not run the same way as gTLDs, which is important to note.
I don't see how those would be any more reliable, since companies generally act in their best interest (which may not always be in your best interest if, for example, you find yourself suddenly competing with them)
