I am using whatsapp form 2016 its amazing applicating till now no. Chatting app can beat it.
It loads with lots of super duper features emojis are to cool in looks and lots of gify are available and the new sticker feature is good and the best part of the whatsapp is its delete from everyone which make it special and funny.
It has clean chatting interfaces with lots of settings available that we can customize it.
And the voice mail system is the most interesting part of the chatting, we can attach file , send photos and audios pdf contacts and lot more stuffs like this no man in earth can hate WhatsApp.
Overall I loved whatsapp & I prefer WhatsApp over any other chatting apps.
