Is the IOS 7 Jailbreak worth it?

My contract is up and I'm contemplating getting the iPhone 5s or 5c. I currently have the iPhone 4 that's still running on IOS 5… I never felt like updating it.
But I've been doing some reading on the new jailbreak and how buggy it is and such. Nowhere has said if you really should or shouldn't. They just say "beware."
The only app that I really want is BiteSMS and maybe the 5 Icon Dock.
Do you think it's worth the jailbreak? Or just the phone and hold off for 7.1 and what's to come of the jailbreak?

IMessages, gamecentre, facetime problem?

Ok, so my family I and share an iPad (4th gen) and I have an iPhone 5s. On the iPad, I put my email in when I was setting it up. My brother always chats on iMessages with his friend. Now I used the same email when I was setting up my phone too. So whenever my brother chats on iMessages with his friend, they're messages come up on my phone too which is really annoying. Also my brother downloaded all these games on the app store and they connected with game centre, so now all these games appear on my game centre and all of my brothers friends come up in my friend list. Also, my brother facetimes his friend. Whenever my brother gets a call from someone, it shows up on my phone too. Its really annoying.
