Should I get Ios7 on my IPhone 4?

I still haven't updated my phone because i hated the look of it, but now i'm debating it.

Loads of people say that on an IPhone 4 or 4s there are loads of troubles with ios7 but this was around when it first came out, is it alright to do it now? I don't want my phone to run slower or use more battery like people say it does.

You will see very little benefit unless you have an iPhone 5. Battery life does not improve. Keep background running programs to a minimum, turn off push technology and blue tooth will help battery longevity

I didn't update my iPhone 4s until recently, I had no reason to slow my phone down for a few extra features, but I did update in the end because:

I got bored and wanted something different.
I wanted to use the latest version of Pages, which required iOS7.

Performance isn't that bad actually.

Your choice, but in my opinion there's a lot more features and its much more helpful. Its a new more colourful polished look and you can slide up and there you can turn on Wi-Fi, bluetooth, etc. And you can also adjust brightness, volume, turn on torch, calculator and all that stuff. You also get a notifications bar when you silde down and you see weather, time, notifications. There's multiple new features. But, only update if you don't mind loosing the space!

IOS 7 provides a more sleeker look to the OS of the phone, in my opinion. You will see some new benefits and changes as well. The new IOS 7.0.4 is the latest update & I must say; I'm pretty impressed with it.
I say go for it!
