I have never had to make this choice with whatsapp but with other programs. What it came down to with me was priority. Privacy was a priority for me. Most people are sheep who don't care. If I were to pick my software based on what friends and family used for software then I may as well give up any desire for privacy right then and there. This may not help you but the TLDR is do what is right for you not for others.
