This question comes up commonly on reddit —- yes iMessage is very popular here. In my experience - Facebook Messenger, Snapchat, Discord are the top messaging services. Whatsapp is not uncommon to be sure, but I would wager a significant portion of users in the United States have it installed because they chat with people overseas. Signal & Telegram are pretty small userbases.
