If you purchase these Feit bulbs, you will suffer the fate of having to replace them in a year.
If you buy regular 60w bulbs, you'll probably have to replace even sooner, they'll consume more electricity, and you'll probably pay more. I've had mixed results with the off-brand cfl bulbs. Some last for years while others out of the same package last less than 1. At 25 cents, it's not that big of a gamble.
