I went through this same debate - liked the look of the 9AN because of rechargeability and the twin level option and of course SF quality...but I was nervous about having to charge outside the body because I knew it would end up failing the "too hard test" and thus it would not perform when I needed it most...
I am a big SF fan and have many of their lights, M2, M3, M6 (recently) E1e, L1, A2 etc... so I am not biased against SF at all....but for my duty carry I use a Tigerlight and keep either the L1 or A2 in my pocket for low level use...
The Tigerlight isn't quite built like an SF, but for this use, it is an awesome product. You get lots of light (I rate it somewhere between M3/225 and M6/250 for output and penetration but others will know the numbers for sure) for managing "encounters" and I can spotlight something in the woods 200ft away without a problem. Run-time for me is just over an hour and charging is easy. (you can get spare batteries for the Tiger, and I have one, but I found it too fiddly to change on a regular basis, so I'll just keep the backup until the first one dies...).
kind regards,
Simon
