Keep in mind these lights have different goals.

Also that there is a broad range of products from SF, some very sophisticated.

While the Fenix lights tend to be brighter, and are great bang-for-the-buck lights, when it comes to reliability and tactical light use, I'd still bet my life on a SF over a Fenix.

This may be changing with the TK10 and TK11, but I haven't seen a critical comparison of these lights in that context. Certainly it is clear the TK10 and TK11 are very good lights and very good values. Are they up to SF standards in regards to reliability? I don't know.

Also keep in mind that a number of the SF lights are essentially "legacy" lights, probably targeted at existing users who have existing fleets to maintain, or people who are familiar with an existing product and don't want to change, or pay more. Also, some don't like the tint of LED lights.

Bottom line is it is good to have options!
