I prefer the one-handed operation of the NovaTac and the Clicky. I like the extra burst mode and lower low of the Clicky, and the extra length makes it more comfortable for me to hold and use. Given the ability to now enable the programming function in the 120E/T, is the Clicky worth twice the price of the NovaTac? Who knows, but I'm happy with the Clicky (prototype) and it's replaced a 120P as my EDC light.
