That is an overly simplistic statement. Yes, all things being equal, a higher cap is better.
But a 14 year product has a lot more risk than a 7 year product. If you fail to grasp those 7 more years of losing access to your money is not a risk, then I'm a bit worried that you are missing the picture.
Risk? There is no more risk of losing money in a 7 year annuity than a 14 year annuity. Everyone went in knowing the surrender penalies, to argue otherwise is non-sensical. Surrender penalties aren't a risk, they are design feature.
