Depending on what data you look at, and your goals of therapy, the answer is different.
If you don't have a history of heart disease, then there is statistically minimal benefit to mortality that can be directly attributable to statin therapy. However, one could argue that just because it doesn't prevent death, it still has other benefits. It for every 100 people that take it, it may prevent 1 heart attack. And for every 150 people that take it, it may prevent 1 stroke. However, for every 10 people that take it, roughly 1 person will develop muscle pain from it.
That being said, looking at the raw numbers is simplistic. Just because it only prevents 1/100 heart attacks, and has no mortality benefit, doesn't mean there is minimal benefit. Heart attacks can also cause morbidity and not just mortality. If you get a heart attack that doesn't kill you, but damages a bunch of heart muscle, your quality of life will decrease.
Another factor is that it reduces narrowing of blood vessels from cholesterol plaques through the body. This may help reduce the risk of erectile dysfunction, may reduce the risk of dementia (although via another mechanism may also cause cognitive issues).
Long story short, diet and exercise should be first line, along with weight loss. But if it was me, I would probably put myself on a low dose statin, or another cholesterol reducing medication in the mean time.
I don't know how old you are, but you could consider a coronary calcium score (which isn't the best marker for coronary health, but is one of the easiest to get).
Hopefully our resident cardiologist chimes in.
