Laser strength is very very important.
I would also recommend handling each for ergonomics and seeing how you like each display and if one is noticeably faster.
I haven’t used those two specifically.
Sig Kilo 2K didn’t do well for me in any kind of inclement weather. Mostly snowing.
Maven RF.1 is absolutely fantastic. Extremely strong laser, if I can see it I can range it. Also returns huge distance readings freehand.
