My guess is that the newer ones are more stable(?) and that they are compatible with more homebrew(????)

The higher the better shit you can modify on your console. Even though Sony patches different thingd throughout updates, it's better to stay up to date with the newer releases.

Okay. So is 4.75 good or 4.70 okay for modding? I will not go higher than 4.80 though.

I never updated my console, I stayed on 4.70 for the fun of it, but yes higher the better. Don't go too high though, since some stuff hasn't been released yet for the higher firmwares. I'd suggest to stick between 4.70-4.75 or whatever it is now.

Got it. Thanks for the help and the info!
