Muffed & Combustible, seem to be dead, Interstellar early development it seems & more geared towards Kbin… Eternity (very good) recently had a update after months of inactivity, whereas Voyager & Thunder (both excellent) have active devs and continuous support & updates…
You can’t really go wrong with either of those, I do lean towards Voyager as a personal preference… Raccoon is another that I really like, but I’m not sure if that will see any further development…🤷🏻♂️
