Bitwarden vs Authy opinions
olavrbBitWarden can be used for TOTP, but it's not included in the free version. So comment from @josephcw and @gholem is not true. See: https://bitwarden.com/pricing/
nxkyesjqcjstrnkecxBitwarden DOES have TOTP as a paid option ($10/yr for personal use). The only caution is if you put all your credentials and TOTP in one place, the purpose of MFA has been defeated.
onkoeBitwarden is great, but it's not a replacement for Authy. It does not provide 2FA services.
calenderBitwarden's 2FA is paid. If you want free, open source and cross-platform app, you can use keepassXC (for pc) and keepassDX(android version of keepass)
Bitwarden is a password manager, not a two factor authentication app.
josephcwBitwarden is excellent software, but it's not for two-factor authentication. The two have completely different uses.
gholemAuthy is a one-time password generator for 2FA whereas Bitwarden is a password manager.

Aegis Authenticator vs Authy opinions
RemovedUserAegis is hands down the best 2FA app for Android. It is Easy-to-use, Clean, Open Source and provides very useful Backups. It also allows you to see the 'Seeds' of the Services which most other services like Authy or Google Authenticator don't provide.
can import from basically any other similar app, has support for Steam OTP, can add Blizzard authenticators (with some work,) much better UI
Best OTP app, great alternative to google and authy. Frequently updated too. Best in class UI
imjohndoeBest authenticator app available on Android. Sleek interface. Fingerprint unlock. Encrypted backups. Your codes aren't being stored on some remote server. What else could you want?
erebosgrIt's open source, uses harder encryption and you can migrate between devices.
It implements Time-based One-time Passwords (TOTP) and HMAC-Based One-Time Passwords (HOTP). Simply scan the QR code and login with the generated 6-digit code.
