I loved being jailbroken, I've been jailbreaking since my iPod touch 4th gen, so I was very used to it and familiar.
But ever since iOS7 I don't miss it AS much. The control panel really helps, makes me miss SBSettings less and SBSettings was one of my favorites.
One thing I really miss are the tweaks I had installed. Loved using activator a lot, Pandora skip tweak, Adblocker, I can't even remember all the tweaks because I had so many. A couple keyboard tweaks, notification/status bar tweaks.
I also really miss Zephyr. I think Zephyr is the biggest thing I hated losing when I upgraded to 7.
But I am definitely going to jailbreak my 5S as soon as it's available and stable. iPhones are even better when you can tinker with them.
