Hi nightwatchman! Well, you know how it its to go to the market and try to get something in just 1 piece! Impossible 
I will only answer about the Zanflare as it is the one I have, and it doesn’t have noticeable PWM.
One thing it has that is not that good is a greenish tint shift (the contrats between the yellow led and the purplish/blueish AR coating on the lens tends to do that).
But you can try to look to other lights before pulling the trigger! The Rofis lights are getting positive feedback around here! You can search for the names and take a look to some reviews too
And then go back to those threads with discounts :money_mouth_face:
I hope you make a choice that suits you the best! Or multiple choices :partying_face:
