It must be noted that whatsapp GB is not available for iOS yet. If you want to use two numbers of WhatsApp accounts on the same device then GBwhatspp is the best app you can use without any issues.
It also has improved privacy and allows you to send GIF messages to your friends.
GBwhatsapp is more flexible than the original chat app as it allows you to use a large variety of themes and chat wallpapers.
