I was once in the same position, questioning the value of Surefires because they didn't really seem to have the best bang for buck value to me. By the time I bought my first Surefire (A2 Aviator w/white LEDs) I had already owned a bunch of Fenix L1/2P, L0P, Nuwai Q3, Arc AAA, LSL/LSH, and my most expensive and prized light (at the time), a HDS U60GT. So I already had a pretty good notion and expectation of what a quality light should be and feel like. The A2 did not disappoint.
It's not the brightest, smallest, technically advanced light, heck, it wouldn't even take rechargeables, but there was something... dare I say...
magical about holding a Surefire for the first time. The build quality is instantly obvious, it just feels right and serious. The HA finishing quality/thickness is awesome, but the color matching is an entirely different story. My HA Natural A2-WH, A2-RD, L4, and E2e are all multi-hued. My A2-WH is 4 obvious different shades of HA natural and there are only 4 physical pieces to it. So if you are picky about color matched lights, then Surefire's HA natural lights are not for you. Their HA black is a bit better but they still won't win any beauty contests. To their credit, these lights are not meant to be beauty queens, they're meant to be used and abused. They are also one of the very, very few manufacturers who under rate their lumen specs. See
this thread for a recent example.
My recently purchased Nitecore D10 & EX10 put my Surefires to shame in terms of HA color matching, output, and small size, but the build quality of the fit and finish still have a ways to go. Surefires also have a proven reliability record (except for the older clickies which aren't as reliable as the old twisties), plus their lego-like modularity and compatibility are second to none. You can take any Surefire E-series tailcap and use it on any E-series body and it will work.
If you are really interested, go to a local gun/knife/army surplus shop that carries Surefires and see if they have some display models you can handle so that you can see and handle it for yourself. Or like someone else mentioned, buy one off BST to try out, something cheap like a 6P with a LED drop-in (not a G2/3xx light, the nitrolin body is totally different from the metal bodied lights) and if you don't like it, put it up for sale again, you won't lose much, maybe the shipping cost and you can think of that as the price to try out a Surefire.
