Each type of life insurance product has its advantages and disadvantages. You can’t say term life is the best, whole life is the best or universal life is the best. It depends on what an individual client need and his or her situation. As a client, they should know all the advantages and disadvantages but of course, they are under the supervision of a certain type of insurance agent that can be biased and try to sell what they have to offer to form their companies. Avoid an agent that focuses on selling one type of product. Talk to an agent who can provide the knowledge of each type and you can choose what best for you.
The best thing to compare permanent life insurance policy to is to another similar type permanent life insurance policy. And you don’t want to focus on the interest rate specifically but on the actual values in each policy that are “guaranteed” – not projected. All things being equal, this tells you which permanent policy is less expensive and provides a higher net interest rate instead.

As for your question, I don’t believe I’ve ever reviewed a USAA whole life policy so I can’t comment on then specifically. I would simply encourage you to start by clarifying your personal goals and to then evaluate each option based on how well it will help you meet them. With that said, of your main goal is investing for retirement then I would typically encourage you to max out traditional retirement accounts before considering any kind of life insurance.
Builder's risk insurance insures against the risk of physical loss or damage to property during construction. Builder's risk insurance is typically written on an "all risk" basis covering damage arising from any cause (including the negligence of the insured) not otherwise expressly excluded. Builder's risk insurance is coverage that protects a person's or organization's insurable interest in materials, fixtures or equipment being used in the construction or renovation of a building or structure should those items sustain physical loss or damage from an insured peril.[28]

Who ever said anything about only having whole life insurance as an investment? Savings, The Market and Insurance (a mix of whole and term) is the best way to plan and protect one’s retirement. Plus once your premiums are paid up, the need to repay the loan is not true. (as long as you don’t go into the death benefit). What the real issues is people are tapping into loans while they are making premiumpayments and they aren’t receiving the proper assessment.
With that out of the way, I’ll point out that I would not even consider selling my best friend whole life. It’s a rip-off in his hands and I value my friendships too strongly to alienate those I love by selling them whole life. I would however sell it to my wife! Why is that? Well, because the commissions on these policies are HUGE. Between the First Year Commission and the override, if I buy the policy for myself or my wife and just roll the commission into additional whole life, it begins to look attractive. That compounding makes it attractive for insurance salespeople in a way that is simply not available for the average consumer. So when your insurance guy says “oh yeah, I own this policy” it’s probably true…but the value proposition is very different for each of you. Beyond this particular case, I’m not a fan of whole life in just about any situation. Go figure then that half the people who attend the Million Dollar Round Table conferences generally sell a lot of this crap. Take from that what you will…
My current blended Whole Life policy breaks even with premium paid in year 5, and together with my Indexed Universal Life policies, my permanent insurance policies constitute my entire fixed income allocation. No need for bonds, as these policies give me a decent long-term growth of between 4.5-6% that is virtually risk free, tax free and dummy proof…and provides a giant tax free death benefit upon my passing.
Any reputable source will report mutual fund and stock returns as “annualized” figures, which takes the sequence of returns into account. Another term for this is “geometric average”, which again accounts for the order in which returns are received. So while there are some financial “experts” out there touting average returns (cough, Dave Ramsey), for the most part what you’re talking about here is not a factor.
