iOS 7.1 vs 9.0 PB on iPhone 5

[Ternary]

I got a spare iPhone 5 laying around that has iOS 7.1 installed (not 7.1.2). I'm thinking about trying the iOS 9 Public Beta on it, but if I do that, I can't go back to iOS 7.1. My only option would be to go to iOS 8.4, which I know from my main iPhone 5 runs slower than iOS 7.1.

With that in mind, do you think trying the beta is worth it? I'm interested in the new features.

Why not just install the Public beta on your main iPhone 5, and if you don't like it go back to 8.4. That way you don't get rid of iOS 7.1 on your spare iPhone 5.

iOS 8.4 is a lot faster than iOS 9.

Last time I heard, it's a bad idea to install a beta OS on your primary device.

If I were you, I'll keep my old iPhone 5 on 7.1, it works way better than any iOS 8 version on it.

I suggest you wait till the general release of iOS 9 in September (~2 more months) before you update your main phone.

Hope you don't let your impatience get the better of you and update your old 7.1 iPhone 5 to 9.0 beta and lose all hopes of getting back to one of the last, most stable version of iOS.

It's a bad idea to install a beta on your daily device and then expect your phone to be problem-free.
There will be glitches and there will be incompatible apps.
As long as you know what you're getting into it's relatively pain-free.
Plus you can always go back to where you were, unlike with your 7.1 phone.
If you're up for an adventure and familiar with restoring, DFU mode, and other bits of iPhone fun then give it a shot.
Or don't.
But I wouldn't mess with the 7.1 phone unless you're happy to lose 7.1.
