It depends what kind of hair and skin you have. Creams can work longer and be a lot easier but they can also burn your skin. Waxing is obviously an option but it hurts and can be expensive and risky if you go somewhere that isn't clean. Razors are easy but time consuming and can irritate your skin. Trimmers are easy and fast but they don't cut the hair as close as a razor.
I personally have really sensitive skin so I stick to shaving and trimming.
