Crimson trace LTG 770 or Streamlight TLR 6?

[OliviasDad]

Both of these seem like good options for a firearm with no rail. I’m just curious which is the most functional? The flashlights on both seem similar but is a strobe(crimson trace) or a red laser(streamlight) the better option? Size and weight seem pretty similar too. Thanks I’m new

I've found more holster options for the TLR6.
