I have and love both. I'll try and do a pros and cons for them(not to many cons though)
SB Pros: Fits larger hands better, battery life seems to be a little longer, the best electric switch around.
Cons: It's BIG, kinda heavy.
Omega Pros: Lightweight, fit a average hand like a glove, great mechanical switch
Cons: Batts seem to drain faster in it than the SB.
Both are awesome topline PVs. If style and longevity are your thing, the omega is probably best. If youre looking for justa great PV that is as tough as a
tank and looks dont matter, the SB is a great choice.
