I have those two! I really prefer the reflector IF22 even though it is a little longer because the beam simply works better in my life and neither is a flashlight I will stuff in a pants pocket.
TIR flashlights to me work ‘best’ on small lights overall. On something larger that needs a holster or backpack, I find the right reflector simply works better for beam evenness, throw, and flood.
TIR and Zoomies to me are really special use case options.
Glad to see you here!
And that flashlight is AWESOME!!! 😎
