Hey guys I'm having some trouble deciding between these two flashlights. I will be leaving it in my car to use. Just how much brighter is the n3 than the g2? I like the fact that the g2 is shorter since it only uses 1 AA, but is it a better investment to get the n3 instead, since I could always switch over to CR123As? Does anybody have both that can give me a comparison? Thanks.
