Should I get ios 7? For my iphone 4?

Ok so the new ios 7 is out, and every one is raving about it. I'm not too crazy about it for I do not like change; I never updated my phone I have ios 5. The reason why i'm asking for advice is because ever since it came out my phone has gotten slower! It lags, freezes, takes forever to upload things, etc, and I never dropped the phone or gotten water damage. I have seen how ios 7 looks. I absolutely hate it, it looks cheap. I feel like its the most laziest upgrade I have ever seen, it looks childish, flat, and not something I would expect an upgrade to look like. Its as if they took a step backwards with this cheap weird animated excuse for an upgrade. Anyway, is it worth it? I feel I may have to upgrade it, so I would like to know you guy's opinion on it. Would I be better off leaving my phone as it is? Or do you know a way I could make my phone faster without upgrading?

At least from my use of ios 7 on my iphone, it is fluent and has no bugs. It is more appealing and I actually like it. I saw it on the apple website and thought oh no this looks awful, but it is actually very nice. In a way I was getting sick of ios and now this has renewed my love for it. I have an older iphone and it runs smooth as silk. So go and download it you'll love it. Hope this helps.
