I haven't compared the two lights but I've compared lumens. I just mounted a TLR-1 w/C4 LED which packs a whopping 300 lumens and I can tell you this, it is amazing. I've used it indoors, also worried about it being "too bright". It isn't. It puts off enough ambient light I can ID a taget without pointing my weapon at them, keeping it at a low ready. It puts out enough light that if I do use it for disorientation, it definitely packs the punch to do so. Plus, I have Streamlights fantastic warranty and customer service. You can have the other lights. It's the TLR-1 for me, without a doubt.
