OS for G350 recommendations

Hey all! I posted about a week ago asking which handheld I should get for my upcoming deployment that doesn’t have BT or WiFi. I would first like to thank you all for the feedback and info given it was beyond helpful!

I settled with the Battle XP G350! What I was hoping you all could give some recommendations for a OS for the system.

I don’t mind the original OS that comes installed but I’m all for a better more intuitive experience! (Also will be taking any good game recommendations, trying to find some games I will have fun playing for the next 9-12 months 😅)

Thanks!
