My social circles use it because it provides a consistent experience. Some have androids, and some have iPhones. When you have an all iPhone group chat, things work rather well. Liking different texts, animations, etc work well. But when you add a non-iPhone to the mix, the texts are sent sms-style, so you get messages that say "Sam liked X's comment!".

It's easier for everyone to use WhatsApp, because that platform provides a consistent experience. Also I can search messages in WhatsApp, I can't find this in iMessage.
