Which iOS for an iPhone 5?

[Draeger]

I'm getting an iPhone 5 free gratis from a relative today to replace my ageing iPhone 4. I was wondering if anyone could recommend me an iOS version to use? Had a quick Google and opinion seems to be split on iOS 9.1 being OK to use?

Ta.

Thanks. Are you on 9.1 or the recently released 9.2?

Also, latest jailbreak available at the moment is for 9.0.1 via Pangu, yeah?
