There is no good reason to ever use Authy. They have the ability to lock your out of your Authy account, thereby locking you out of every account which you use 2FA for, which is a massive red flag. And the only way to unlock your account in such a scenario? Complete KYC with them. 
Oh, and they track your activity and share that info with third parties.

I just found out the details about the Authy 2FA App, I've been using it for about the last 2 years and still haven't encountered any problems, because I've never deleted the app or moved it or Synced to a second phone. Oh, and they track your activity and share that info with third parties.-snip-
But if you say that there's no reason to use Authy, maybe I'll give Aegis a try as you suggest.
Currently I am also still using Google Authenticator and Authy.
and now I'm thinking more about securing and updating my 2FA security though still haven't found any issues in Authy.
