Should I upgrade to IPhone 5s?

I have a Samsung Galaxy s3 and I'm wondering if should upgrade to Iphone 5s. My phone runs slow and I've done everything to make it faster but didn't work. I don't care for andriod and when I'm surfing the web without Wi-Fi, my phone always says error has occurred. Would be worth the money to upgrade to Iphone 5s?

IPhone 5s (s) means SAME SH! TTT

True! C for cheap. Which really is not…
N S for same… Take my word. Get n HTC one. It's fast. It's beautifully made. I like it… Before you buy any phone look up it's reviews first…

Honestly you should just wait for the 6 if you want a iPhone that bad but just get the 5… The 5s isn't much different
