Why not have both?
The truly excellent reflectors offer both. Surefires being the best combination of both throw and flood.
Pelican M6 LED reflectors offer both too, but seem to be a little more tuned to throw. Excellent flawless beam quality like a Surefire though.
If I can only have one, give me flood. But in most cases, one can get both (if you don't mind sacrificing--when you get both you lose having one or the other being outstanding--instead you compromise and have both be good).
The beams that are pure throw with little useful sidespill I find practically useless. At close range, a bright tiny spot is too bright and small to be useful, and at further ranges they do okay at distance, but don't light up enough area for my liking.
