Many CFL bulbs are junk. Their "years" claim assumes they are only used for brief periods each day, and even at that I doubt they can reach their warrantee period. That doesn't matter though, because you will be unable to find any mechanism for contacting the manufacturer about the warrantee. I assume they have zero claims.
LED bulbs are different. Heat is a killer. You might be burning them up in an enclosed or even partially enclosed fixture.
I've equipped 4 homes completely with CFL bulbs -- every single bulb but the oven, range hood, and refrigerator. Home #1 was in '99. I usually buy whatever is a good deal at Wal Mart and whatever major hardware store is nearest, trying small batches until I find a color/temp in a bulb that I like. I've had maybe a dozen bulbs fail during that time, including dumb breakage. And we run these things hard, often 8-to-12 hours a day in some of the living spaces in winter.
Whenever I see CFL threads, there's always some who claim they never last long. I don't know what these folks do to their bulbs, but for me they've lasted many, many years. Certainly long enough to pay for themselves in savings over incandescents -- and then some.

Even if you read the fine print saying "if used 3 hours a day", and divide the stated lifetime by 8 (even though they don't stay on 24 hours a day), they still don't last that long.

If they can't function in the same environment as a standard bulb, that seems like a major design defect. And on top of that, even the ones used in mostly-open lamps don't last noticeably longer.
