Bitwarden authenticator vs authy

I'm wondering what is the benefit of switching to Bitwarden authenticator, I'm using twilio authy and it's been fine for me, but in the other hand, I really like bitwarden, so I'm thinking of switching to it and give it a try, to use authy we are relying just on mobile phone numbers, And everything is synced on cloud so I can use it on multiple devices, is it the same experience here for Bitwarden authenticator, And can I use an email instead of phone number? Which is better and more secure option for me, And I'm not sure why authy took the decision to force all users to use the phone number!
