It depends, I have the Preon, the Stylus Pro, the C4, and the Microstream and they all work well for me, I also have the Terralux Lightstar 80 which is along the same lines but higher lumens than the Stylus. The big advantage to the Stylus and Lightstar is the momentary on function which I really like for my daily vehicle inspections. The Preon is nice for having the three main power settings. Is the Preon worth the price yes, but so are the Stylus Pros and I honetly tend to use them twice for every time I use the PReon.
