It depends on the size and geometry of the head and reflector itself. If you compare two lights like the IF22 & IF22A, the IF22 has a head about twice as tall to accommodate the reflector while the IF22A gets nearly the same throw with a TIR and shorter head. So the reflector throws farther but the flashlight is longer.
If you want the most throw possible you’ll need a deep reflector. Though when considering form factor TIRs might be the best in their weight class.
