SST Ultrafire C3 Q5 vs Jetbeam I IBS/Nitecore Defender Infinity

[Tekno_Cowboy]

Although I know that the electronics in the Jetbeam/NDI are far superior to those in the Ultrafire C3, how do the bodies compare? Is the Jetbeam/NDI still sturdier/higher quality even though it's aluminum, or is the SST of the ultrafire going to hold up to more abuse? Please keep in mind that if I get the Ultrafire, I will be swaping out the lens, tail switch, and control board at a minimum, and still end up about $25 cheaper than the Jetbeam/NDI.
