Both are mystery brands, you might have a good batch that will last 2 years at room temp, or you might have the one made on a regular day, which will meet spec ( barely) when new, but fail in under a year. If used in undemanding applications ( like on a mains transformer supply doing 500mA max) and well derated they might last 2-3 years before failing. I have used them before, and they are only good for low demand applications where you do not need low ESR or high current handling or even capacitance stability.
