Finally giving up on Jerboa

I've had enough of the text editing issue, where when you press backspace it highlights the space before the word and ends up deleting it. The developer passes off responsibility for this to the engine they use and seems to have no intention of addressing it.

What are the pros and cons of the other Android apps? I'm only considering ones on F-Droid, not the Play Store, so that rules out Summit and Boost. Ones I have available are:

• Thunder (IzzyOnDroid)
• Interstellar (IzzyOnDroid)
• Voyager
• Eternity
• muffed (IzzyOnDroid)
• Combustible
