I have a 4S with 6.1.2 jailbroken and am wondering about upgrading before 7.1 comes out and Apple closes the door on the 7.06 jailbreak, is it worth it? does it work reliably ?

I have an iPad on IOS 7 so I know about IOS7 but just wondering how well the jailbreak works. Is it best to use Evasion still or are there other better jailbreaks now, googling brings up a huge list of possibilities and the guide here doesn't seem to have been updated in a while.

Appreciate any feedback
