Yes, but one of the best alternatives until Ladybird is ready.

Librewolf, Vivaldi, Orion (iOS and macOS only) are all solid options.

To me something Chromium based is just not a good alternative, since you'll still play in Google's hands.

Librewolf is based on Firefox. If Firefox dies then Librewolf is done as well.

Orion is Webkit-based, which is not too bad, but as you said it's ios and macOS only.
