Too many variables
Sorry, but there is no single "Best" mode of carry for everyone, any more than there is a single "Best" handgun, type food, vehicle, or type spouse for everyone.
As to carry, much depends on your body type, life style, and the clothing you wear on a daily basis. If you're willing to wear a cover garment such as a suit or sport jacket every day, the choices are far simpler. If not, you must become more choosy about how and where you pack your pistol.
I carried a 1911 type inside my waistband for years. As my age became more advanced, and when I lost some weight, I began having problems with the pressure the pistol and holster put on some nerve. It caused leg numbness in a short time, and later intense pain. This had to do with my body type, and might or might not pertain to some other individual.
Several years before I retired, I settled on the Bianchi Minimalist belt slide holster for every day wear of my Commander. It rides high, pulls the pistol against my side, and allows for rapid access. This arrangement requires a cover garment. Since I retired, I've been carrying a .38 snub in my pocket far more often than the full size service pistol. this allows me a lot more latitude in the way I dress.
I can only suggest that you try as many different holsters as possible, to see what suits you best.
Best regards,
