My precious is a Zebralight 600 something or another. Good flood with variable levels and looong run time. I use it, among other things for bedtime reading when i tuck myself in.Looking at it last night, i thought, "This is way better than my carbide lamp of yore" (which is still a valued antique on my mantel....)
No experience with the other brands, but I'll bet they are a leap forward over the other alternatives. I am considering a headlamp that takes AAs or 14500s when small size and weight is critical.
