HTS Sense is bumming me out since I'm used to pure 4.1 on my Nexus 7, but it's easy to modify without rooting.
If you want to disable the pull ring, go to:
Settings > Personalize > Lock Screen Style > No Lock Screen. Though, if you choose "no lock screen", it takes a couple seconds to actually load your home screens. I might just stick with the pull ring to avoid that.
If you want the pin/pattern/face recognition, go to security and set one of those up; then set "Lock Phone After" to "Immediately". That way, it'll prompt you whenever you turn your screen on.
If you don't mind paying for apps, TeslaCoil has a great customizable one called "WidgetLocker". Switched out the HTC ring for a custom JB
