I generally prefer to prepay a year. It tends to knock a bit off the price, and is less annoying, as I'm not constantly getting notices of withdrawal. Many companies will actually refund the unused portion, if you cancel early.
However, lifetime subscriptions seem to be almost worthless, as I have yet to encounter a company that doesn't redefine "lifetime," to mean the lifetime of the subscription, which ends, whenever they want.
